Conrad Gessner, Swiss botanist and zoologist (died 1565)

Conrad Gessner was a Swiss physician, naturalist, bibliographer, and philologist. Born into a poor family in Zurich, Switzerland, his father and teachers quickly realised his talents and supported him through university, where he studied classical languages, theology and medicine. He became Zurich's city physician, but was able to spend much of his time on collecting, research and writing. Gessner compiled monumental works on bibliography and zoology and was working on a major botanical text at the time of his death from plague at the age of 49. He is regarded as the father of modern scientific bibliography, zoology and botany. He was frequently the first to describe species of plants or animals in Europe, such as the tulip in 1559. A number of plants and animals have been named after him.
