Cornelius Drebbel Tanya Makarova 11 b
Cornelius Jacobszoon Drebbel was born in Alkmaar (Netherlands) in 1572, the son of a well-to-do farmer. He probably received only an elementary education, which would have included Latin. He had no university education. Biography
As a young man he was apprenticed to the famous engraver Hendrick Goltzius in Haarlem. Goltzius incidentally practiced alchemy and undoubtedly introduced Drebbel to the art. Drebbel had little interest in the quest for the Elixir of Life or the Philosopher's Stone, and instead learned chemical ideas and processes. Biography
Biography In 1595 he settled at Alkmaar, where he devoted himself to engraving and publishing maps and pictures. He soon turned to mechanical invention, for in 1598 he was a granted a patent for a pump and a clock with perpetual motion. In 1602 he was granted a patent for a chimney. He also made instruments and designed a water-supply system for the town of Alkmaar.
Drebbel's most phenomenal work was definitely the submarine. In 1620, he made the first "rudimentary" submarine. Drebbel constructed his vessel while working for the British Navy. They never used it, but tested it many times. The submarine
The submarine He had a wooden row boat; it had a wooden hull wrapped tightly in waterproofed leather. His row boat was the first to answer the question of air replenishment underwater. Air tubes with floats went to the surface to provide the craft with oxygen. Oars went through the hull at leather gaskets. Twelve oarsmen and some other passengers were on board. The trip at the Thames River took three hours.
The submarine Drebbel went on to build two more submarines, each one bigger than the last. The final model had six oars and could carry 16 passengers. It was demonstrated to the king and thousands of Londoners on the Thames, and could stay submerged for three hours at a depth of 15 feet.
