Ludwig Haberlandt

Ludwig Haberlandt (1 February 1885 – 22 July 1932) was an Austrian scientist, who is known as a father of hormonal contraception. In 1921 he carried out experiments on rabbits and he demonstrated a temporary hormonal contraception in a female by transplanting ovaries from a second, pregnant, animal.

His father was the eminent botanist, Gottlieb Haberlandt, plant tissue culture theorist and visionary; his grandfather was the European 'soybean' pioneer and trailblazer Friedrich J. Haberlandt.
