Andreas Vesalius Andreas Vesalius - The Founder of Modern Human Anatomy. Before Vesalius, human anatomy was not learned by studying or dissecting bodies. Much of the knowledge was fictional, chiefly contributed by Galen over a millennium ago. Vesalius was the first to challenge the theories of Galen and carried out dissection to closely observe the inner structure and construction of the human body. Based on his direct observation through dissection, Vesalius discovered, recorded and published the facts of real anatomy.

Gyroscope The first instrument used more like an actual gyroscope was made by German Johann Bohnenberger, who first wrote about it in 1817. At first he called it the Machine. Bohnenberger's machine was based on a rotating massive sphere.n the 1860s, the advent of electric motors made it possible for a gyroscope to spin indefinitely; this led to the first prototype heading indicators, and a rather more complicated device, the gyrocompass. The first functional gyrocompass was patented in 1904 by German inventor Hermann Anschuetz-Anschütz. kaempfe
