What 15 Groundbreaking Inventions Looked Like When They First Came Out
It’s not clear who first invented microscopes, but they emerged around the 1590s with few of the bells and whistles they have today.
Two different sources are credited with the invention of the microscope: Hans Lippershey, who filed the first patent for a telescope in 1608, and Hans and Zacharias Janssen, a father-son team who wrote about microscopes in the 1590s.
Bicycles were made out of wood when they were first invented in 1817 by Karl von Drais.
Karl von Drais’s early bicycle required riders to push the contraption by foot. Other inventors then added pedals in the 1860s.
