Fritz Haas (January 4, 1886 – December 26, 1969 in Hollywood, Florida) was a Jewish[1] German zoologist born in Frankfurt am Main.
He was trained in biology by herpetologist Oskar Boettger (1844–1910) and malacologist Wilhelm Kobelt (1840–1916).
From 1911 to 1936, he was a curator of invertebrate zoology at the Senckenberg Museum in Frankfurt am Main.
[2] He identified and cataloged specimens that had lain unexamnied since the 1893 World Columbian Exposition, starting to build the museum's now world-class collection of aquatic invertebrates.
He performed extensive field investigations in Norway (1910), Pyrenees, Spain, France (1914–19), southern Africa (1931–32; as part of the Hans Schomburgk expedition) and the Americas (Brazil, Bermuda, Cuba, Canada).
