Gaspard Bauhin

Caspar Bauhin (1623), Pinax Theatri Botanici, page 291. On this page, a number of Tithymalus species (now Euphorbia) is listed, described and provided with synonyms and references. Bauhin already used binomial names but did not consistently give all species throughout the work binomials.

Jean and Gaspard were the sons of Jean Bauhin (1511–1582), a French physician who had to leave his native country on becoming a convert to Protestantism. Gaspard was born at Basel and studied medicine at Padua, Montpellier, and in Germany. Returning to Basel in 1580, he was admitted to the degree of doctor, and gave private lectures in botany and anatomy. In 1582 he was appointed to the Greek professorship in the University of Basel, and in 1588 to the chair of anatomy and botany. He was later made city physician, professor of the practice of medicine, rector of the university, and dean of his faculty.

The Pinax theatri botanici (English, Illustrated exposition of plants) is a landmark of botanical history, describing some 6,000 species and classifying them. The classification system was not particularly innovative, using traditional groups such as "trees", "shrubs", and "herbs", and using other characteristics such as utilization, for instance grouping spices into the Aromata. He did correctly group grasses, legumes, and several others. His most important contribution is in the description of genera and species. He introduced many names of genera that were later adopted by Linnaeus, and remain in use. For species he carefully pruned the descriptions down to as few words as possible; in many cases a single word sufficed as description, thus giving the appearance of a two-part name. However, the single-word description was still a description intended to be diagnostic, not an arbitrarily-chosen name (in the Linnaean system, many species names honor individuals, for instance).

In addition to Pinax Theatri Botanici, Gaspard planned another work, a Theatrum Botanicum, meant to be comprised in twelve parts folio, of which he finished three; only one, however, was published (1658), long after his death. He also gave a copious catalogue of the plants growing in the environs of Basel, its flora, and edited the works of Pietro Andrea Mattioli (1500–1577) with considerable additions. His principal work on anatomy was Theatrum Anatomicum infinitis locis auctum (1592).
