From 1919 to 1955, Richard Frey was head of the
Finnish Museum of Natural History. He was primarily interested in
Diptera and he described many new species in this Order. He studied exotic insects as well as those of Finland, especially those of
Madeira and
Cape Verde. Frey acquired by exchange or purchase many collections, notably the Georg Böttcher (1865–1915) collection of Philippine Diptera. When he retired, the University of Finland purchased his collection for the museum.
