Jean-Georges Baer (12 February 1902[1] – 21 February 1975[2]) was a
Swissparasitologist and environmentalist.
Born in England,[2] he studied in
Neuchâtel,
Geneva, and in
Paris, where he worked with
Charles Joyeux.[2] His book "Ecology of animal parasites" (1951) is considered a classic in the field.[3] Baer published more than 250 articles,[3] among them fundamental work on
Temnocephalida (a kind of
flatworm parasite) and on
tapeworms.[4]
Baer was a member of several scientific societies, vice president of the International Union of Biological Societies,[4] and from 1958 to 1963 president of the
International Union for Conservation of Nature (IUCN).[5]
