Friedrich Ruttner (15 May 1914 – 3 February 1998) was an Austrian SA-member, NSDAP member, SS-physician, neurologist, zoologist and bee expert.
As a former member of the NSDAP (Nazi Party), membership number 6360728, before and after the Anschluss, the SA (Brownshirts) and the SS, he was dismissed from university service in 1945 by order of the Allies, due to their policy of denazification.
[2][3] The following year, together with his brother Hans he founded the Institute for Bee Science in Lunz am See in 1946, which soon became part of the Ministry of Agriculture.
[7] Ruttner wrote, among other works, the Natural History of Honeybees[8] He further developed the method of morphometry in order to distinguish between different subspecies of Apis mellifera.
However, the morphometric differentiation of the subspecies is difficult and the assignment of many regional forms depends on the exact measuring method.
