Haberlandt, Gottlieb

Haberlandt, Gottlieb 

Born Nov. 28, 1854, in Mosonmagyaróvár, Hungary; died Jan. 30, 1945, in Berlin. German plant physiologist. Son of F. Haberlandt. Corresponding member of the Academy of Sciences of Berlin, Vienna, and Munich and the Leopoldine Academy.

After graduating from the University of Vienna (1876), Haberlandt worked in Tubingen and, starting in 1877, at the University of Vienna. A professor at the University of Graz (1888-1909) and the University of Berlin (1909-23), he was one of the founders of physiological plant anatomy. He worked out a system and terminology of plant tissues according to their physiological role—mechanical, conductive, assimilative, and so on. Haberlandt studied plant tropisms and irritability phenomena. He discovered the so-called wound hormones, products of cell decomposition that stimulate cell secretion.
