Popular Science Monthly/Volume 44/January 1894/Obituary Notes


Traugott Friedrich Kützing, a pioneer in the scientific study of the Algæ, died at Nordhausen, September 9, 1893, in the eighty-seventh year of his age. His latest work is more than twenty years old, and all his most important works appeared before 1851. Yet, although much that he did and taught has been superseded or supplemented by more recent investigations, his Phycologia generalis, published in 1843; his Tabulæ phycologiæ, published in twenty volumes, 1845 to 1870; and his Species Algarum, 1849, are still standard works. His extensive collection of dried Algæ has long been in the possession of the University of Leyden.

Dr. Alexander Strauch, Director of the Zoölogical Museum of St. Petersburg, who died in September, 1893, at the age of sixty-one years, was an authority on reptiles and the author of several zoological works.

Prof. Hermann August Hagen, of Harvard College, a distinguished entomologist, died in Boston, Mass., November 9, 1 893. He was born in Königsberg, Prussia, where his ancestors had been connected with the university for two hundred years, and, having pursued his studies there and at other places, settled there in the general practice of medicine. He was assistant in the surgical hospital there and incumbent of local civil offices when he was invited by Prof. Agassiz to come to Cambridge as assistant in entomology at the Museum of Comparative Zoölogy. In 1870 he was made Professor of Entomology at Harvard. His first scientific paper was published in 1834. His publications include more than four hundred articles, of which the most important is the Bibliotheca Entomologica.
