German zoologist and anatomist (1831–1910)
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.

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", 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. In 1875, he was named a full professor and successor to Max Schultze as director of the anatomical institute at Bonn.

He is credited with coining the terms spermatocyte (1876), spermatogonium (1876) and spermatid (1886). 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.

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". 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.
