Leading Moravian sheep breeders, who joined with university professors and
other educated citizens to form a Sheep Breeders' Society in 1814, looked t
o science to provide a reliable basis for breeding. Their activities reache
d a climax in the 1830s, when they defined and focused on heredity as the c
entral research goal. Among the members taking part was Abbott Cyrill F Nap
p, who in 1843 would accept mendel into the monastery. The contributions of
Abbot Napp to the sheep breeders' view of heredity are here described. Aft
er 1900, when Moravian animal breeding sought to embrace Mendelism, in comp
etition with other theories, a major influence was exerted by Jaroslav Kriz
enecky (1896-1964). In 1963, Krizenecky accepted responsibility for establi
shing the Mendel Museum (Mendelianum) in Brno as a vehicle for historical r
esearch into the origin and essence of Mendel's discovery.
