Anonymous: Two leaders in science, Gard. Chron., 3 : 40 : 164, 1906. Weigmann, Arend Joachim Friedrich No published biography of Wiegmann has been found. The following facts have been gathered from several sources, but chiefly from a seminary paper presented by Charles Chupp before the department of plant pathology of Cornell University in 1913. A copy of this paper is to be found in the library of Cornell University. Wiegmann was born 1771; died 1853 in Braunschweig. He was examined for assistant chemist by the Imperial College in Braunschweig in 1795, and appointed associate pharmacist to the chief apothecary there.. From 1821 on he lived as a private druggist in Braunschweig, but having taken his medical degree in 1827, he was appointed to a pro- fessorship there. He began his studies in plant pathology in 1798, his first contribution in this field being apparently his, Versuch einer Krankheitslehre der Gewachse, which appeared in the first three volumes of Sprengel's, Land- und Forstwissenschaftliche Zeitschrift, which formed the basis of his text-book issued in 1839 (see footnote 1, p. 37). He also interested himself in, and wrote papers on, plant hybridization; the nature and origin of peat; and the inorganic constituents of plants. The following references give some few facts regarding him: Ascheron, P., and Graebner, P., Synopsis der Mittel-Europaischen Flora, 6:2: 1086, footnote, 1910; Flora, 36 : 288, 1853; Bot. Zeit. 11 : 279, 280, 1853. A fine lithograph portrait is to be found in the Van Kaathoven collection of medical men in the library of the Surgeon General's office, Washington, D. C.
