Johannes Japetus Smith Steenstrup (1813–1897) was a Danish zoologist, biologist, and professor. Born in Vang (Thy) on March 8, 1813 he held a lectorate in mineralogy in Sorø until 1845 〔Brockhaus' Konversations-Lexikon. 14th ed., Leipzig, Berlin and Vienna 1894; Vol. 15, p. 219〕 when he became a professor of zoology at the University of Copenhagen. He worked on a great many subjects, including cephalopods, but also in genetics, where he discovered the principle of the alternation of generations in some parasitic worms in 1842. Steenstrup discovered (1842) the possibility of using the subfossils of the Postglacial as a means of interpreting climate changes and correlated vegetation change, which he called succession in the recent past.〔Cowles, Henry C. (1911) The causes of vegetational cycles. Annals of the Association of American Geographers, 1 (1): 3-20 ()〕 Two of Steenstrup's students, Christian Vaupell and Eugen Warming further developed this line of research. Japetus Steenstrup was a professor to zoologist Johan Erik Vesti Boas, who was also a student of zoologist Carl Gegenbaur, and Hans Christian Gram, inventor of the Gram stain. 〔 "Biographical Etymology of Marine Organism Names. B" (biographies of scientists with names beginning "B"), Hans G. Hansson, TJärnö Marine Biological Laboratory, Göteborg University and Stockholm University, ''TMBL.gu.se'' webpage: (TMBL-P-Etymol-B ). 〕 During Charles Darwin's extensive study of barnacles (Cirripedia) between 1846 and 1854, he corresponded with Steenstrup, who sent him both information and specimens. Darwin returned the specimens in 1854, and by way of thanks also sent Steenstrup a box of specimens, with a letter listing the 77 species of cirripedia he had enclosed as a gift. The specimens were dispersed in the Natural History Museum of Denmark, but in 2014 they found the list and were able to find most of the specimens for a new exhibition of their best objects. When Darwin published his series of monographs, he included notes acknowledging his debt to the kindness of Professor Steenstrup for sending him specimens of both modern and fossil barnacles. Together with Johan Lange, Steenstrup was the publisher of ''Flora Danica'' fasc. 44. In 1857, he was elected a foreign member of the Royal Swedish Academy of Sciences. He died on June 20, 1897 in Copenhagen. ==References== * Steenstrup, J.J.S.
