Georg Wolfgang Knorr was a German engraver, naturalist, and one of the first paleontologists of the 18th century.
Knorr was first apprenticed to his father as a lathe operator, and at the age of eighteen became a copper engraver for Leongard Blank, working with Martin Tiroff on the illustrations for Jacob Scheuchzer's Physica Sacra (1731). This work and his acquaintance with J.A. Beurer, a mineralogist and correspondent of the Royal Society, awakened Knorr's interest in natural history.
In the 1750s Knorr began publishing his own sumptuous folios. One of the most beautiful books of the eighteenth century is devoted to sea shells.
Charles Robert Darwin was an English naturalist, geologist, and biologist, widely known for contributing to the understanding of evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history, and he was honoured by burial in Westminster Abbey.
