On July 18, 1635 (according to the old Julian calendar), English natural philosopher, architect and polymath Robert Hooke was born. He is known for his discovery of the laws of elasticity, now known as Hooke's law. Hooke did research in a remarkable variety of fields. He was one of the first men to build a Gregorian reflecting telescope and to suggest that Jupiter rotates on its access. His studies of microscopic fossils are what led him to be one of the first proponents of a theory of evolution.
On November 14, 1797, Charles Lyell, British lawyer and the foremost geologist of his day, was born. Lyell was a close friend to Charles Darwin and is best known as the author of Principles of Geology, which popularised James Hutton's concepts of uniformitarianism – the idea that the earth was shaped by the same processes still in operation today.
In 1908, the 'Jena Phyletic Museum' was giftet to the University of Jena due to its 350th anniversary by Ernst Haeckel. The famous zoologist was best known for his approaches in evolution theory.
