Theophrastus (c. 370–c. 285 BC)
Theophrastus was a Greek philosopher of the Peripatetic School, a pupil of both Plato and Aristotle, generally considered the father of modern botany. His Enquiry into Plants deals with description and classification, his Plant Etiology with physiology and structure. But he is best known for Characters, a collection of 30 brief character sketches, often satirical.
