The Senckenbergische Naturforschende Gesellschaft bought his extensive collection (including type material from other arachnologists such as L. Koch, Eugène Simon, Thorell, Philipp Bertkau and Friedrich Dahl) and his private library.
The name commemorates the German physician and scientist Philipp Jakob Cretzschmar who founded the Senckenberg Natural History Museum.
Johann Christian Senckenberg (28 February 1707 – 15 November 1772) was a German physician, naturalist and collector.
