Adolph von La Valette-St. George

Adolph von La Valette-St. George (14 November 1831 in Schloss Auel – 29 November 1910 in Bonn) was a German zoologist and anatomist, known for his research in developmental biology.

Adolph von La Valette-St. George

He studied at the universities of Berlin, Munich and Würzburg, where he was a student of Albert von Kölliker. In 1855 he obtained his PhD with the thesis "Symbolae ad Trematodum evolutionis historiam",[1] then in 1857 received his medical doctorate. In 1858 he qualified as a lecturer at the University of Bonn, where in 1862 he became an associate professor.[2] In 1875, he was named a full professor and successor to Max Schultze as director of the anatomical institute at Bonn.[3]

He is credited with coining the terms spermatocyte (1876), spermatogonium (1876) and spermatid (1886).[4] Some sources mention La Valette-St. George as the first to observe what would later be known as the Golgi apparatus (1865, 1867), a structure that he reportedly described in the sexual cells of snails.[5][6][7]

Published works

With Heinrich Wilhelm Gottfried von Waldeyer-Hartz (from 1874) and Oscar Hertwig (from 1889), he was co-editor of the journal "Archiv für mikroskopische Anatomie".[8][2] The following are a list of some of his noted scientific works:

  • Entwicklung der Trematoden, 1859 – Development of trematodes.
  • Studien über die Entwicklung der Amphipoden, 1860 – Studies on the development of amphipods.

gollark: Thanks, this is probably enough to implement a thing.
gollark: Ho!
