BAUHN, Gaspard, brother of the former, was born in 1560. He was early devoted to physic, and pursued his studies at Padua, Montpellier, and some of the celebrated schools of Germany. In his journeys he collected a number of plants which had escaped his brother's notice. Returning to Basil 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 that university, and in 1588, to the anatomical and botanical chairs. He was at last made city-physician, professor of the practice of medicine, rector of the university, and dean of his faculty. Thus distinguished and honoured, he acquired great reputation. He became eminent as a botanist, and was aided in his researches by the contributions of his disciples and friends in various parts of Europe. Haller gives him the character of being assiduous and laborious in collecting plants, by which he surpassed his brother in number of them, and also in the accuracy of his figures; but he possesses less acuteness of judgment in distinguishing varieties, and detecting the same species under different names. He published several works relative to botany, of which the most valuable is his Pinax Theatri Botanici, seu index in Theophrasti, Dioscoridis, Plinii, et botanicorum qui a seculo scripserunt opera, plantarum sere sex millionum nomina cum synonymis et differentiis. Opus XIV. annorum, 410. The confusion that began to arise at this time from the number of botanical writers who described the same plant under different names, rendered such a task as this highly necessary; and though there are many defects in the execution, the Pinax of Bauhin is still a useful key to all writers before his time. Another great work which he planned was a Theatrum Botanicum, meant to comprise twelve parts, fol. of which he finished three, but only one was published. He also gave a very copious catalogue of the plants
growing in the environs of Basil; and he edited the works of Matthiolus, with considerable additions.
Gaspard also wrote on anatomy, which he studied under Hieronymus ab Aquapendente, and pursued with vigour during his youth. The principal is Theatrum Anatomicum infinitis locis auctum, 410. Frankf. 1621; which is a kind of pinax of anatomical facts and opinions. He also published a collection of anatomical plates. He died in 1613.
