AUGUST WEISMANm 



August Weismann, a foreign member of 

 this society, was born at Frankfort on the 

 Main, January 17, 1834, and died at Frei- 

 burg in Breisgau, November 6, 1914. He 

 early showed the traits of a naturalist and 

 in one of his books speaks of the excitement 

 he felt as a boy in catching butterflies. He 

 attended the University of Gottingen, where 

 he studied chemistry and medicine, coming 

 especially under the instruction of the dis- 

 tinguished anatomist Henle, and receiving 

 the degree of M.D. in 1856. After spend- 

 ing three years at Rostock as an assistant 

 he began the practise of medicine at Frank- 

 fort and during this time he visited Vienna 

 in 1858, Italy in 1859 and Paris in 1860. 

 From 1861 to 1862 he was private physician 

 to Archduke Stephan of Austria at Scham- 

 burg Palace. He then studied zoology at 

 Giessen under the renowned zoologist 

 Leuekart and became privat-doeent in zool- 

 ogy at the University of Freiburg in 1863, 

 where he spent the remainder of his life. 

 In 1866 he was appointed professor ex- 

 traordinarius and a few years later became 

 professor ordinarius, which position he con- 

 tinued to hold until a few years before 

 his death, when he was made professor 

 emeritus. 



In person he was a man of striking ap- 

 pearance, being about six feet tall and well 

 proportioned and having a fine head and 

 face and an earnest but kind expression of 

 the eyes. From 1864 to 1874 and again 

 from 1884 on he suffered from an eye 

 trouble which interfered greatly with his
