COVER

Our cover depicts Erich von Tschermak-Seysenegg (1871-1962), a man , long cited as one of the three rediscoverers of Mendel's work. Recently, however, his claim to a share of the honors along with Correns and De Vries has been challenged (see, for example, Monaghan and Corcos, J. Hered. 77:468-469. 1986.). Nevertheless, Tschermak is amply distinguished on other grounds to warrant a place on our cover. The rendering, by Ms. Elaine Gotham of our Publications staff, is from a photograph which appeared in Genetics, Vol. 37 (January 1952). The photograph was taken at a late stage in Professor Tschermak's life. Accompanying the photograph in Genetics is an account of Tschermak's life and works written by the late George H. Shull, himself a famous geneticist/breeder.

Born in Vienna in 1871, Erich von Tschermak was a member of an intellectually distinguished family. He was the grandson of Eduard Fenzl, a professor of botany under whom Gregor Mendel studied. Tschermak gained considerable experience in practical plant breeding both before and after receiving his Ph.D. at Halle in 1896. In Ghent, in the spring of 1898, he began his studies with the hybridization of garden peas. He continued this work upon returning the next year to Esslingen, near Vienna. A paper summarizing his results was read in January 1900.
Dr. Tschermak experimented with many major crop plants during his professional career, making numerous valuable contributions to breeding and genetics and earning a host of honors and awards. During this time he published important papers relating to the genetics of Pisum (1901, 1902, 1904, 1910, 1912, 1916) including the discovery of several genes.
