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",[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]
