Cornelis Drebbel Jacobszoon (1572–7 November 1633) was a Dutch scientist who developed the first submarine navigation system in 1620. Drebbel was a pioneer in the creation of measuring and control systems, as well as optics and chemistry. He has a minor lunar crater named after him. He was the creator of the first submarine to incorporate Leonardo da Vinci's designs.
Biography
Cornelis Drebbel Jacobszoon studied in Alkmaar for a number of years before moving to Haarlem, which is also in the north of the Netherlands, around 1590. Hendrick Goltzius (sculptor, painter, and humanist), Karel van Mander (painter, writer, and humanist), and Cornelis Corneliszoon from Haarlem were among the Academy's teachers. Drebbel honed his sculpting skills.
In 1595, he married Hendrick Jansdotter Goltzius' sister Sophia Jansdotter Goltzius. They are the parents of four children. Drebbel was at Middelburg in 1600, where he constructed a fountain at Noorderpoort.
Cornelius met with Hans Lippershey, the telescope's constructor and Zacharias Janssen's collaborator, at Noorderpoort. Drebbel investigated optics and lens grinding. Around 1604 the Drebbels came to England, most likely at the request of James I of England, the new king (VI of Scotland). Drebbel also worked as a court reporter.
Drebbel and his family were invited to Emperor Rudolf II's court in Prague in 1610. Drebbel returned to London after Rudolf's death in 1612. Drebbel was in financial problems after his sponsor, Prince Henry, died.
Early Inventions of Submarines
Leonardo da Vinci (1452-1519) drew the first sketches of submarines, while William Bourne devised the ship's plans (1578). Cornelius van Drebbel, on the other hand, was the one who succeeded in constructing it in 1620.
He only viewed the sketches drawn by his two friends at first. Then van Drebbel gradually attempted to realize the sketch, which he considered to be exceptional. Bourne's sketch is still used as a building standard. Specifically, when the ship's tank is filled with water, the ship can sink.
The water tank must be emptied first before the ship can be brought to the surface. Then, using oars as propulsion, van Drebbel attempted to apply Archimedes' law. Van Drebbel is still working on improving his handmade submarine.
Especially in terms of design, by shaping it into a two-boat arrangement and covering it with leather. The paddle holes have been made more sticky to prevent water from entering. Van Drebbel didn't use a ballast system and instead tried to make the boat simpler to dive by using iron.
The submarine went on to become the world's oldest submarine. Because animal skins and timber frames still make up the body. Van Drebbel also used leather to wrap the boat's oars and wrap the boat's bottom with waterproof material.
To deliver oxygen, Van Drebbel attached an air tube. On the Thames, he made his maiden trip with 12 oarsmen. During these tests, the ship was able to dive as deep as 360-450 cm for 2-3 hours beneath the River Thames in London.
Van Drebbel's final model featured six oars and could hold 16 passengers. The boat can dive for three hours and sail up to 12-15 feet (4-5 meters) beneath the water's surface. The railway runs from Westminster to Greenwich and back.
The submarine, which resembles a cigar, is designed to be hydrodynamic. When sinking, hydrodynamics, according to van Drebbel, can reduce drag. The ship will sink more slowly this way. The submarine travels at a speed of roughly 18 kilometers per hour.
Submarines designed by van Drebbel are currently being developed for military use. Especially as a submarine for war. This is not at all what Drebbel had in mind when he first built a submarine. He didn't want his submarine to be a weapon of mass destruction.
Optics
In 1619 Drebbel designed and built the telescope and microscope and was involved in a building project for the Duke of Buckingham. William Boreel, the Dutch Ambassador to the UK, mentions the microscope developed by Drebbel.
Towards the end of his life, in 1633, Drebbel was involved in a plan to stream fans around Cambridge, while living in a near-poverty running ale house in England. He died in London, England.
