Boris Karlovich Stegmann (or Shtegmann) (Russian: Борис Карлович Штегман: 25 December 1898 – 28 December 1975) was a Russian ornithologist of German descent who worked on zoogeography and introduced the idea of faunal affinities or "faunal types" to subdivide the palearctic region.
But after the beginning of World War II he was expelled from Leningrand and forced to work in Kazakhstan.
He published a key to the bird families of the Soviet Union and took a special interest in the corvids.
[3] In 1978 a manuscript on the comparative anatomy of the avian forelimb was published posthumously with a preface by Walter Bock.
[4][5] In 1951 he wrote a biographical memoir which was briefly printed but destroyed by political censors.
