In 1900, Vienna was the capital of the Austrian-Hungarian
Empire and a centre of both science and the arts: The names of Theodor
Billroth, Karl Landsteiner, Sigmund Freud, Ludwig Boltzmann, Ernst Mach,
Arthur Schnitzler, Robert Musil, Karl Kraus, Gustav Klimt or Otto
Wagner are linked to pioneering work in the fields of medicine, prychology,
physics, philosophy, literature, fine arts and architecture, to mention just
a few disciplines.
The laws of inheritance, published by the Augustinian monk Gregor Mendel in 1865 and 1866 in Brno, remained largely ignored until 1900, when time was ripe for their "rediscovery" by the German botanist Carl Correns, the Dutch botanist Hugo De Vries and the Austrian agronomist Erich von Tschermak-Seysenegg. While Correns and De Vries were mainly interested in theoretical concepts such as the mutation theory, Tschermak recognized the practical value of these laws and applied them for developing new cultivars of crop plants. So, 100 years ago, Tschermak contributed to a considerable rise of agricultural plant breeding and to an increased publicity of applied genetics.
Erich Tschermak (1871-1962)
and his scientific achievements in the field of applied genetics are nearly
forgotten at present. Therefore, the goal of this documentation is to retell
Tschermak's story and to present him as a scientist and plant
breeder. First of all, the "independent" rediscovery of Mendel's laws
by Correns, De Vries and Tschermak in 1900, which has been
criticized and questioned by historians of science, is revisited. "Open questions"
will be raised in the light of new evidence on that matter.
Materials about Tschermak
A scientific exhibition on Tschermak-Seysenegg was presented at the University of Agricultural Sciences Vienna, Gregor Mendel Str. 33 (A-1180 Vienna, Austria) between July 20 and September 15, 2000.
2. CD-ROM (in preparation)
A CD-ROM containing all materials presented through the exhibition as well as numerous documents found in the estate of Tschermak at the Archive of the Austrian Academy of Sciences and in the Tschermak-collection of the University of Agricultural Sciences Vienna, is under preparation at present.
