    5 of the World’s Deadliest Shipwrecks

    You usually think of the Titanic when you hear the word “shipwreck.” The impact of this tragedy was so great that a film was produced to honor it. Did you know, though, that it’s not even the deadliest natural disaster ever recorded? Some of these tragedies have, sadly, slipped into obscurity over time because they were not highlighted enough, despite the importance of the responsibility of remembrance. I have compiled some of history’s worst shipwrecks here. Make yourself at home, for whether they were the consequence of human cruelty or negligence, the reading is not going to be a breeze.

    MV Doña Paz

    Built in 1963, the MV Dona Paz passenger ferry sank after colliding with the MT Vector on December 20, 1987.

    The first shipwreck we will talk about is considered the deadliest in peacetime. This is the shocking story of the Doña Paz, where thousands of passengers tragically lost their lives.

    What Was Doña Paz?

    The Filipin ferry known as “Asia’s Titanic” had done nothing by the book. In other words, this disaster could have been prevented. On December 20, 1987, more than 4,000 passengers departed from the Tacloban port en route to Manila.

    The ship’s capacity was only 1,525 passengers and 58 crew members, leaving hundreds of people to find themselves sleeping in the hallways or on the deck. This may sound surprising, but for the Philippines, where overcrowded ships were common, it was not a shocking situation.

    How Did the Tragedy Unfold?

    Due to the ship’s non-compliance with specifications and its lack of proper communication equipment, we can’t have a precise account of what happened. The events described below are the result of an in-depth investigation into the tragedy, and the time frames are approximate.

    On the evening of December 20, 1987, at around 10:00 PM, Doña Paz collided with a petroleum tanker named Vector in the Tablas Strait near Marinduque Island. The collision caused one or two explosions, and the spilled petroleum from Vector caught fire.

    The flames spread to all sides of the overcrowded ship filled with people and goods, leading to a full-blown panic. The crew was helpless in providing any assistance or reassurance to the passengers running in every direction, and some even jumped into the water. There was no way to rescue them, and not a single lifeboat had been deployed. The ship’s lack of proper communication equipment also meant that emergency services could not be alerted. It wasn’t until the following morning, approximately 8 hours after the accident, that authorities were informed. By the time they reached the wreckage, another 8 hours had passed, and a horrific death toll had been recorded. Thousands of victims perished in the flames or drowned.

    The Death Toll

    The aftermath of tragedy.

    This horrific maritime disaster received much less attention than the Titanic but resulted in three times as many casualties. Determining the exact number was difficult, especially considering the illegal passengers on board. After extensive investigations, it was estimated that 4,386 people lost their lives. From the Doña Paz, 4,317 passengers and 58 crew members lost their lives and 11 from the Vector. There were 26 survivors: 24 from the ferry and 2 from the tanker.

    The cause of death for most victims was either drowning or burning. The majority of the bodies had severe burns, and the sharks in the area ate most of them.

    Today, there are still some suspicions about the exact cause of the tragedy. However, what is known is that neither ship met technical specifications, and Vector lacked detection equipment to see the approaching ferry at its bow.

    While the victims’ families continued to file charges against Sulpicio Lines for “criminal negligence,” they have yet to achieve a result. The maritime company, now renamed the Philippine Span Asia Carrier Corporation, is still responsible for numerous ship accidents in the last decade.

    RMS Lusitania

    The second tragedy on the list is considered a war crime by the United States. In fact, it’s even said that the sinking of the Lusitania was a driving force behind American involvement in World War I against the Germans.

    What Was the Lusitania?

    In the early 1900s, an increasing number of travelers wanted to make transatlantic journeys. At the time, the British dominated the sea transport market, and the Cunard Line had introduced the Lusitania, one of the largest and fastest ships of its time. This colossal ship operated numerous roundtrips between the Americas and Europe, carrying goods, mail, and passengers.

    On May 1, 1915, the ship set sail from New York to Liverpool with 2,165 civilian passengers. Given the Titanic’s sinking three years earlier, most passengers were concerned. However, the crew, who described the ship as unsinkable, quickly reassured them.

    How Did the Tragedy Unfold?

    First, we need to briefly discuss the situation in Europe in 1915. The British and French had imposed a blockade on Germany at sea, and the Germans responded by declaring unrestricted submarine warfare in British waters.

    In this wartime atmosphere, the Lusitania set sail on May 1. However, eight days earlier, the captain had been warned that if he didn’t raise the American flag, the ship risked being sunk by the Germans. But the crew, believing that the enemy would never attack ordinary civilians, didn’t take these threats seriously.

    On May 6, Lusitania received a warning call about submarines on its route. To avoid attracting attention, the ship should have been accompanied by escort vessels. However, it was already too late. Walter Schwieger’s U-20 and its crew of 35 men had already spotted the Lusitania near the coast of Ireland.

    On May 7, 1915, at around 2:25 PM, the submarine fired a torpedo at the ship, which caused an initial explosion. A second, more potent explosion followed this. Passengers who were having lunch panicked and rushed to the lifeboats, which were either overturned or collided with each other. Some desperate mothers even threw their children into the sea, hoping they might survive.

    The ship sank in a terrifyingly fast 18 minutes. When help arrived, most passengers had already been pulled into the depths without a chance to escape, while others had perished from hypothermia.

    The Death Toll

    The toll was horrifying: 1,198 passengers lost their lives, including 128 Americans. The submarine commander, Walter Schwieger, earned the nickname “baby killer” because many children had died in the sinking.

    The then-U.S. President Woodrow Wilson accused the Germans of committing a war crime and attempted to seek revenge by joining the Allied Powers. The slogan “Remember the Lusitania” was used even in future submarine warfare. The Germans always claimed that they thought the ship was carrying ammunition, trying to justify their actions. The wreckage of the Lusitania lies at a depth of 90 meters off the coast of Ireland today.

    Sultana

    The third shipwreck is considered the deadliest accident in American history. You’ve probably never heard of the Sultana. But this story is much more tragic than the Titanic. Unfortunately, this horrifying event has been overshadowed by these two historic events, as it occurred just 13 days after the assassination of Abraham Lincoln and during the final weeks of the American Civil War.

    What Was the Sultana?

    The Sultana was a massive commercial steamship, considered the safest paddlewheeler on the Mississippi. The incident took place right at the end of the American Civil War, just after the Union Army had achieved victory, and most of the prisoners were being sent home to the North via ships.

    The American government had promised $5 to various ship captains for each soldier sent home. Captain James Cass Mason of the Sultana saw an opportunity to make a significant profit and loaded the ship with approximately 2,300 people. Most of these passengers were Union soldiers traveling from Ohio to Cairo, Illinois.

    The captain likely believed there was nothing to worry about and considered it a good deal for everyone. However, the ship was only designed to carry 376 people, making it dangerously overloaded.

    How Did the Tragedy Unfold?

    As the Sultana sailed near Memphis, Tennessee, a tragedy occurred on the night of April 27, 1865, around 2:00 AM. One of the Sultana’s four boilers exploded, causing the other two to explode as well. It appears that the steam boiler had not received proper maintenance, and an unrepaired crack led to the ship sinking.

    During the explosions, hundreds of passengers fell into the water, and a significant portion of the ship collapsed, resulting in numerous casualties. The remaining crew had no time to escape, as the ship caught fire along with the survivors. Since there were no lifeboats or life jackets on the Sultana, there was no means of escape for the unfortunate crew.

    The Death Toll

    This tragedy claimed the lives of more than 1,500 people, most of whom perished in the flames. Whether the explosion resulted from inadequate maintenance or the ship’s overload remains uncertain to this day.

    MV Wilhelm Gustloff

    MV Wilhelm Gustloff

    The fourth shipwreck on the list was by far the most tragic and deadliest in history. The tragedy of the German ship Wilhelm Gustloff claimed more lives than the Titanic, six times more.

    What Was the Wilhelm Gustloff?

    Let’s take a look at the background. It was the year 1944, the peak of World War II, and the Russian army was advancing on German soil. Along the way, they were causing a horrific famine by burning Prussian territories and committing rape and murder.

    German civilians were frightened and desperately trying to escape. They were surrounded on all sides, and the only escape route was the sea. Adolf Hitler initiated Operation Hannibal to send civilians and soldiers back to their home countries.

    Wilhelm Gustloff, nicknamed “Hitler’s Titanic,” appeared to be a carrier of hope when it departed from Gotenhafen. This prestigious Nazi ship left the port on January 30, 1945, bound for Hamburg. Officially, there were 6,050 passengers on board, but unofficially, there were many more. While the exact number remains uncertain, approximately 10,000 refugees crowded onto this ship, symbolizing hope and a sense of being saved.

    How Did the Tragedy Unfold?

    On the first day, Wilhelm Gustloff sailed cautiously in Baltic waters, aware that the probability of encountering Russian submarines was high. Indeed, several submarines were reported on the first night.

    To avoid coastal mines, the ship sailed further out and followed a well-known route. However, in a fatal decision to avoid unexpected collisions, they turned on the navigation lights. This mistake cost the lives of thousands of passengers because it made the ship easily detectable.

    By 6:00 PM, it was already too late. The S13 submarine, under the command of Alexander Marinesko, identified the German ship. By 9:00 PM, it had entered firing range and fired four torpedoes that would have deadly consequences due to the lack of armor plating.

    Panic prevailed on the ship. Passengers were fleeing in all directions. Many people died in the explosions, and with the water rising at an alarming rate, they had no time to climb to the upper decks. In just a few minutes, the massive ship tilted to the port side, rendering half of the escape chutes unusable.

    Because it was colder than usual at that time of the year, people in the water died within minutes. The ship sank in less than an hour.

    The Death Toll

    In this horrific shipwreck, 9,000 people lost their lives, and 996 people were rescued. It was the deadliest maritime disaster of all time. Alexander Marinesko, the person responsible for this massacre, was posthumously awarded the title of Hero of the Soviet Union on May 5, 1990. He is still wrongly seen as a war hero today.

    MV Le Joola

    The last shipwreck on the list is a tragic incident that has unfortunately been largely forgotten in the media. However, Le Joola is one of the deadliest disasters in history, and the cause of this tragedy is human negligence.

    What Was Le Joola?

    Le Joola was a ferry that connected Dakar to Ziguinchor in Senegal. Due to tensions between Casamance and the rest of Senegal, the Senegal Ministry of Armed Forces seized the ship in 1995.

    Due to the neglect of the ministry, the ship’s condition deteriorated. Despite being banned from sailing in 2000, it continued to operate roundtrips. On the fateful day of the tragedy, the vessel was in an extremely bad state. Furthermore, more than 2,000 passengers had boarded the ship, not the recommended 550. On September 26, 2002, this overcrowded and poorly maintained vessel set sail.

    How Did the Tragedy Unfold?

    The ill-fated day of September 26, 2002, would be etched into the collective memory of the Senegalese people. The boat was navigating in difficult weather conditions with heavy tropical rain and extremely strong winds.

    Less than an hour before midnight, a strong wind off the coast of Gambia caused panic, with the crowd trying to get inside. Then there was an electrical failure. Mamadou Dieye, one of the survivors of the shipwreck, said, “We couldn’t see anything on the boat. The screams still echo in my ears.”

    The overcrowding caused the ship to capsize in less than ten minutes. Many passengers were trapped and drowned before they could make their way out. The number of life jackets was insufficient, and some passengers tried to cling to the hull of the Joola. The remaining ones drowned while waiting for the rescue team, which arrived almost twelve hours later, at 8 in the morning.

    The deadly delay was not only due to the lack of communication equipment on the ship but also because some ministers who were informed of the situation during the night failed to respond.

    The tragedy was entirely human-made. The poor condition of the ship, disregard for safety regulations, overcrowding, and the inadequacy of rescue teams resulted in the loss of thousands of lives.

    The Death Toll

    A total of 1,863 people lost their lives, with 65 survivors. Only 600 bodies could be recovered. The Senegalese people are fighting for the annual remembrance of the incident so that it is not forgotten, but unfortunately, that is all they can do. The families of the victims are angry, and some believe that this tragedy could have been prevented, filing complaints against the Senegalese government for negligence.

    The government didn’t even keep its promise to provide aid to the thousands of orphaned children left behind by the shipwreck.

  • In 1875 an American Spy Plotted to Kill Hundreds for Insurance Payment

    In 1875 an American Spy Plotted to Kill Hundreds for Insurance Payment

    At about 11 a.m. on December 11, 1875, a massive explosion took place in Bremerhaven. Just then, the last of the cargo was being put onto the steamer “Mosel,” which was about to depart for Southampton and then continue on to New York.

    Most of the passengers were southern Germans who were looking to leave their homeland and begin a fresh life in the United States.

    The “Mosel” was a North German Lloyd (NDL) steamer. NDL was the largest German shipping firm, rivaling even the Hamburg America Line (HAPAG). Both businesses relied heavily on immigrants as a revenue source, alongside freight.

    The pier and other areas of Bremerhaven were destroyed when an explosion shook the area in the winter of 1875. A 13-foot-deep (4-meter) crater was all that remained.

    There were at than 80 fatalities and hundreds of injuries. Where did all of this terribleness come from? When the dust settled, everyone knew the explosion had happened on the hull of the ship. The calamity had been triggered by a “hell machine” buried in the barrel, according to preliminary investigations.

    Moving to a New Place

    The immigrants crossed the ocean on the massive steamships of the shipping firms, which were increasingly replacing sailing ships at the period. Liner service between continents became feasible with the advent of swift steamers, which were less reliant on the wind. The Atlantic crossing took between 10 and 14 days.

    This meant that by the time World War I broke out, more people were leaving Europe than ever before. The shipping industry reaped huge financial benefits as a result. The annual influx of German immigrants to the United States averaged over 120,000 in the 1880s. By the turn of the century, they had become the most numerous immigrants to the United States.

    The majority of immigrants traveled across the Atlantic in steerage since it was the least expensive but most uncomfortable option. Steerage passengers were not afforded the same luxuries as those in first and second class. Bedframes were instead lined up and then shifted to the side on the return journey to make room for more freight. The “Mosel,” a freight and passenger ship that provided liner service between Bremerhaven and New York, was not finished until 1872. Almost seven hundred people could fit on the tween deck.

    The ship was set to leave for Southampton and then New York on the day of the accident. 600 people to be on board. But the NDL steamer “Deutschland” had recently sunk on December 6 after running aground on a sandbank outside the mouth of the Thames, prompting the crew to make an emergency stay in England. Fifty or more people had lost their lives because of the incident.

    Reasons for the Mosel Disaster

    The survivors were brought to Southampton, where they awaited transport to the United States on the next vessel, called the “Mosel” from Bremerhaven. But then things took an unexpected turn for the worse. There was still a cart at the dock, loaded down with boxes and barrels. One of the barrels was constructed from iron-shod, dark brown wood.

    According to the bill of lading, the container weighed 1.3 tons and included high-priced iron components. Today, it seems likely that the barrel fell into the road after slipping from the grip of a port worker operating a crane.

    There was a huge bang. It is hard to piece everything together, but it is understood that the collision activated an ignite mechanism in the barrel, which contained lithofracteur (an explosive compound of nitroglycerin). While the original dynamite recipe was developed by Alfred Nobel (1833–1896), the Lithofracteur explosive combination had more explosive potential.

    Several hours after the explosion, a man was discovered critically injured in a first-class cabin and sent to the hospital. First responders assumed he had been killed in the blast, but then they discovered a pistol inside the cabin with two empty rounds. It seems the man had attempted suicide. A quick check revealed that the barrel in question was really his.

    For Fraudulent Insurance Claims

    The guy’s name was Alexander Keith Jr., and he was a Canadian of Scottish descent. As William King Thomas, he traveled over Europe. Keith, who had accumulated a lot of debt, decided to conduct insurance fraud as a means of getting out of his financial bind. Keith paid a hefty premium to insure a shipment of useless goods that was certain to be destroyed in a bombing raid at sea.

    However, the bomb wasn’t supposed to detonate for a few days, somewhere in the middle of the Atlantic. He preferred to get off the ship at Southampton, where he thought the survivors from the sinking of the “Deutschland,” the “Mosel,” would also be able to embark.

    Keith was gravely hurt in the incident and later admitted his guilt, but he passed away on December 16th, five days after the incident, thus he was never brought to justice. The Bremen police department’s examination of the case uncovered disturbing information.

    By 1873, Alexander Keith was already plotting to murder hundreds of people in return for a large insurance payout. In that year, he went to a watchmaker and asked him to construct a mechanism that could operate quietly for a few days before triggering the detonator with a hard blow. He bought the explosives while pretending to be a Jamaican mine owner.

    By the way, the assault on the “Mosel” was his third attempt. He had previously planted a bomb aboard the NDL ship Rhein in the summer of 1875. He was disheartened to learn that the ship had made it to New York but that the firing mechanism had seemingly failed.

    Because no other shipping company would take his shipment without first checking it, he made the trip to Bremerhaven to give the “Mosel” a go. Unfortunately, the transportation firm took the box anyhow. Since no further suspects could be located and Alexander Keith was already dead, the inquiry was closed in 1878.

    These days, few people remember what happened during the incident. Unfortunately, it seems that not even the little metal plate that marked the site of the disaster near the entrance to Bremerhaven’s New Harbor has survived.

  • The First Submarine Was Invented by Cornelis Drebbel

    The First Submarine Was Invented by Cornelis Drebbel

    The Dutch inventor and engineer Cornelis Jacobszoon Drebbel, who designed and built the first submarine, is pretty much unheard of today by many people. But because of how brilliant he was and how well he understood how nature and chemistry worked, he is rightly thought of as one of the most successful and well-known inventors of the 17th century. Drebbel created and constructed the first submarine in 1620, making it one of his most important innovations. Drebbel’s wooden submarine, driven by oars, was built to stay submerged for hours. It was one of the first submarines that could actually be used, and it led the way for more sophisticated submarines to be built in the years to come. Drebbel’s work on submarines paved the way for undersea exploration.

    How did the Drebbel submarine work?

    The crew members untied the bladders and sucked out all the water before rowing to the surface. The submarine was therefore able to safely descend to depths of around 13 to 16 feet (4-5 meters) for several hours. A rudder allowed for control, while four oars propelled the boat forward by being fed into the water via leather seals.

    Why did Cornelis Drebbel invent the submarine?

    Initially, Cornelis Drebbel created his submarine to help humans learn more about the marine environment, but he quickly realized its potential as a military weapon as well. However, it took another 150 years for them to see action in naval conflicts.

    How did Drebbel’s Perpetuum Mobile work?

    It worked by reacting to changes in the pressure and temperature of a contained liquid or gas. These variations provided the power required to get the gears going as long as possible. Without an external force, it wouldn’t be considered perpetual motion.

    The English king commissioned Cornelis Drebbel

    Drebbel was invited to King James I of Scotland and England’s court in 1604. At the period, academics were more often asked to present their knowledge and abilities. Theologians and alchemists were welcomed in addition to scientists. But, the invitations were still rarely from abroad. The overseas journey had some benefits since the English monarch was inspired enough by Drebbel’s efforts to collaborate with him.

    In that year Drebbel was summoned to England to show his impressive “Perpetuum Mobile” device to King James I (1566–1625). As the news about this fascinating perpetual motion clock spread, Drebbel gained a huge reputation and began to receive invitations from other European countries to showcase his device.

    Between 1620 and 1624, Drebbel built the first functional submarine on a commission from the English king. Drebbel built three effective submarines in total during the period.

    How Drebbel invented the world’s first submarine

    drebbel replica first submarine
    Drebbel’s most advanced submarine is on display at Heron Square in the Richmond-upon-Thames neighborhood of London.

    Drebbel’s greatest achievement was that he designed and made an invention that he owes his reputation to today: The world’s first submarine. Unfortunately, there is no original drawing of Drebbel’s invention to date. Nevertheless, there are close estimates and calculations of how the submarine could be built with a contemporary eye. Between 1620 and 1624, while working for the British Royal Navy, Drebbel made three different forms of submarines. He tested all three in London, on the River Thames. According to witnesses, the latest submarine was able to remain submerged for 3 hours at 13 to 16 feet below the surface.

    In front of King James I and a large crowd of Londoners, he showed off his third submarine. The submarine made a round trip from Westminster to Greenwich. It was the first true submarine in history.

    Drebbel’s wooden submarine was best characterized as a wooden round canoe-style rowing boat. The stern seemed to be the fin of a giant fish, and the oars protruded directly through the hull. It was a lovely figure, smiling and amazed. On the Thames River, the boat did its maiden dive. While rowers ensured that the boat was pushed, it is still not officially known how the crew was given air.

    Cornelis Drebbel tried to persuade the British Royal Navy to use his submarine in naval combat. Despite his relationship with the royal family, the Navy was not interested in this proposal. For submarines to be used for military purposes, 150 years had to pass.

    How did Drebbel’s submarine work?

    Very large pouches made from pigskin used in these submarines were filled or emptied with water, this would allow the boat to go down or up in the water. The wooden double-hull submarine had holes sealed with waterproof leather, in which oars were placed.

    The third and largest boat or submarine developed by Cornelis Drebbel could accommodate 16 people, including 12 rowers. The hull was covered with oiled leather to provide waterproofing. Some records suggest that there were long pipes on the boat that could reach all the way to the surface to provide air for the rowers. There is also evidence that Drebbel created a chemical reaction by heating potassium nitrate which produced oxygen for rowers.

    Oxygen produced by burning

    According to the legend, the crew spent nearly three hours underwater. Drebbel must have thus considered adding fresh oxygen to the waterproof vessel. There are a few hypotheses for this, but the most plausible one is that when saltpeter, or nitrate, is heated, oxygen is released. Drebbel was an expert alchemist long before he worked on the first submarine, so the notion isn’t outlandish in and of itself. The details are still speculative since nothing was really written about his invention and rumors about it were passed around orally. As a result, the legends surrounding this submarine are still unclear.

    Cornelis’ career was eventually furthered by chemistry; he later worked on explosives for the Royal Navy. In summary, Drebbel had come a great way and would remain in England for a considerable amount of time before passing away in London on November 7, 1633. In a number of Dutch towns, including Amsterdam, Delft, Alkmaar, and The Hague, he has streets named after him. Cornelis Drebbel has a minor lunar crater named in his honor as well. Cornelis Drebbelweg, a street in Delft, the Netherlands, is named in his honor.

    Who was Cornelis Drebbel?

    Cornelis Drebbel is best known for the invention of the very first submarine.
    Cornelis Drebbel is best known for the invention of the very first submarine.

    The map artist, painter, engraver, and lens maker, Cornelis Drebbel was born as the son of a wealthy farmer in Alkmaar, The Netherlands. However, he received very little formal education. Although he picked up the basics of the Latin language in his later years, he probably only received a primary education and did not go to university. Drebbel was skilled at conducting numerous experiments despite lacking a formal education.

    At the age of 20, Drebbel began working as an apprentice in the Harlem workshop of Dutch painter, engraver, and publisher Hendrick Goltzius (1555–1617). During his apprenticeship where he also lived in Goltzius’ home, Drebbel had the chance to learn much more than engraving. He learned the subtleties of alchemy, and throughout his life, his work was determined by four elements: Earth, air, water, and fire.

    Drebbel returned to Alkmaar in 1598 and began to work on some versatile inventions. In 1604, he exhibited the first invention that would bring him fame. This was a dazzling astronomical clock machine called Perpetuum Mobile. In his patent application, Drebbel stated that the device could work for years without a visible power source.

    Perpetuum Mobile was an astronomical almanac showing the time, day, date, phases of the Moon, the positions of the Sun, and the positions of the planets. This interesting device was powered by changes in air pressure and temperature. Cornelis Drebbel, of course, was aware of the delicacy of this phenomenon but was delighted with the mystical atmosphere created around his Perpetuum Mobile.

    On the emperor’s request, Drebbel visited the Prague court of Rudolf II in 1610. Rudolf appointed him Chief Alchemist after seeing his amazing perpetual motion device; Drebbel really just claimed that it could rewind continuously due to variations in air pressure. It contained a sealed glass tub where liquid would expand and contract, allowing the clock to perpetually spin backward.

    Cornelis Drebbel’s other inventions

    Cornelis Drebbel also experimented with light and lenses. In 1630, Drebbel developed the first version of the “projector,” an early form of magic lantern or slide projector, and also one of the first microscopes. Both devices used special lenses, which were produced by a machine of his design. Drebbel’s microscope had visibly improved features compared to its predecessors and was an important advance in the field of microscopy.

    From 1604 until his death, Drebbel exhibited many new or improved inventions. Among them was a process for making red paint. This technology was used for many years after Drebbel’s death. Drebbel also made a boiler with a thermostat. It was a thermostatic mobile furnace for the Dutch army; a kind of ventilation system that is exhibited today at Westminster Hall in London; and also, an automatic incubator. This thermostatic furnace is the first known self-controlled device or instrumental control system in history.

    Drebbel invented a rather primitive but still very significant thermometer. But this thermometer device wasn’t put together based on the idea that the compressed air in the glass tube would expand and contract. Instead, Drebbel’s invention was some kind of a thermoscope. The thermoscope was a device that gave insight into temperature without a scale to aid measurement. At about the same time, at least three experimenters were working on an air thermoscope. But what distinguishes Drebbel from them was that his device could be used to control thermostatic devices. Drebbel’s furnace had a major influence on later scientists.

    The use of precision thermometers in the 18th and 19th centuries helped scientists better understand the behavior of substances and contributed to the development of the concept of energy.
