In 1907, Vernon Lyman Kellogg described Fleischmann as the "only biologist of recognized position, of whom I am aware, who publicly declares disbelief in the theory of descent."[4] Palaeontologist William Berryman Scott noted that because of his anti-evolutionary views, Fleischmann was "almost entirely alone in modern biological literature."[5] His anti-evolutionary writings were criticized by biologist August Weismann and zoologist Sinai Tschulok.[2][6]
Fleischmann married Franziska Kiefl in 1902, they had one son, Rudolf. He was involved in forming Erlangen bee breeding institute in 1907.[1] He was the author of a popular zoology textbook and a book which contained a series of lectures held in 1921–1922 at the University of Erlangen.[6] He retired in 1933.[1]
