Georg Ulmer

Georg Friedrich Franz Ulmer (born March 5, 1877 in Hamburg , † January 15, 1963 ibid) was a German entomologist , zoologist, bryologist and limnologist .

After the early death of his father, the son of a primary school teacher also became a teacher in Hamburg in 1899 after he had attended the teachers' seminar. As the eldest son, he also had to look after five brothers and two sisters. In 1934 he was forced to retire for political reasons after the National Socialists came to power and lived in Hamburg-Rahlstedt .

With the exception of a few collecting trips to southern and central Germany around 1900, he stayed in northern Germany and the area around Hamburg, where he specialized in aquatic insects. First he collected in the Eppendorfer Moor and other bodies of water and wetlands around Hamburg. At first he dealt mainly with beetles, later intensively with caddis flies (trichoptera). Besides about insects (besides caddis flies especially mayflies ) he also published on limnology , freshwater fauna, mosses, freshwater sponges and palaeontology (caddis flies in amber in a monograph 1912). He was considered a leading expert on caddis flies and edited many foreign collections in correspondence around the world. 174 scientific publications come from him.

He had been an honorary doctorate from the University of Basel since 1912 (at the instigation of Friedrich Zschokke ). In 1951 he became an honorary member of the Royal Entomological Society of London and in 1959 he was awarded the Federal Cross of Merit 1st Class. He was an honorary member of the German Entomological Society and received the title of professor from the city of Hamburg.

He wasn't married. He lived for a long time with his mother and, most recently, bedridden sister whom he cared for. Ulmer lived from his meager pension in modest circumstances (which made postage for scientific correspondence, reprints and mailing of insects a problem and did not allow him to have a large library) and worked with simple resources.
