Conrad Gessner (also Konrad Gesner, Conrad Geßner, Conrad von Gesner, Conradus Gesnerus, Conrad Gesner; 26 March 1516 – 13 December 1565) was a Swiss naturalist and bibliographer. He was well known as a botanist, physician and classical linguist. His five-volume Historia animalium (1551–1558) is considered the beginning of modern zoology, and the flowering plant genus Gesneria and its family Gesneriaceae are named after him. A genus of moths is also named Gesneria after him. He is denoted by the author abbreviation Gesner when citing a botanical name.

Gessner was born on March 26, 1516 in Zürich, Switzerland, he was the son of Ursus Gessner, a Zürich . Gessner's father realized he was clever, and sent him to live with a great uncle, who grew and collected medicinal herbs for a living. Here the boy became familiar with many plants and their medicinal purposes which led to a lifelong interest in natural history.

Gessner first attended the Carolinum in Zürich, then he entered the Fraumünster seminary. There he studied Latin classics. In school, he impressed his teachers so much that a few of them helped sponsor him so he could further his education at universities such as Strassburg and Bourges (1532–1533). One even acted as a foster father to him after the death of his father at the Battle of Kappel (1531). After the death of his father he left Zürich and traveled to Strasbourg. Here he broadened his knowledge of ancient languages by studying Hebrew at the Strasbourg Academy. In 1535, religious unrest drove him back to Zürich, where he made an imprudent marriage. His friends again came to his aid and enabled him to study at Basel (1536).
