Bruckman, Francis Ernest

, a German physician and botanist, was born at Mariensbal, near Helmstadt, Dec. 17, 1697, and having completed his studies, was created doctor in medicine there, in the year 1721. As his taste inclined him to botany, he travelled over Bohemia, Austria, and a great part of Germany, examining and collecting plants indigenous to those countries, and other natural productions. In return for his communications to the Academia Nat. Curios. and of Berlin, he was made corresponding member of those societies. Having finished his travels, he settled at Brunswick, where he died March 21st, 1753. When young, and before he had taken the degree of doctor, he published: 1. “Specimen Botanicum, exhibens fungos subterraneos, vulgo tubera terræ dictos,” Helmst. 1720, 4to, with engravings. 2. “Opuscula Medico botanica,Brunswick, 1727, 4to. In this he treats of the medical qualities of various vegetable productions, among others, of coffee, the use of which he condemns. 3. “Epistolæ Itineraries,” containing his observations on vegetable and other natural productions, collected during his travels, in which we find a great body of useful information. 4. “Historia naturalis τȢ ΑσβεσθȢ ejusque preparatorum chartæ lini lintei et ellychniorum incombustibilium,” Brunsw. 1727, 4to. In this he has discovered that the asbestos is susceptible of printing, and he had four copies of the work printed on this species of incombustible paper. 5. “Magnalia Dei in locis subterraneis,” a description of all the mines and mineralogical productions in every part of the world, Brunswick, and Wolfenbuttel, 1727, and 1730, 2 vols. fol. 2
