Louis Jacobsohn-Lask

Louis Jacobsohn-Lask ca.1901

Louis Jacobsohn-Lask (born March 2, 1863 in Bromberg ; † May 17, 1940 in Sevastopol ) was a German neurologist and neuroanatomist .

Life

Louis Jacobsohn was born as the youngest son of the master saddler and retailer Jacob Jacobsohn and his wife Henriette, nee. Heart, born. He had a twin sister, Recha, and at least one brother, Hermann; nothing more is known about his siblings. In the 1870s the family moved to Berlin.

Jacobsohn-Lask worked from 1894 to 1904 in the Anatomical Institute Wilhelm Waldeyer at the Friedrich-Wilhelms-Universität Berlin. Before that, he was an assistant at Emanuel Mendel's Neurological Institute , which was affiliated with the university, but not a part of it.

In 1901 he married the later writer Berta Lask .

In 1904 he returned to Mendel and after his death in 1907 he took over the management of the institute. At both Mendel and Waldeyer he worked closely with the Polish neurologist Edward Flatau , with whom he also became friends. Louis Jacobsohn-Lask emigrated to the Soviet Union in 1936 and died in Sevastopol. An honorary funeral was prepared for him, and a Red Fleet chapel accompanied the coffin to the cemetery.

Create

Jacobsohn-Lask's main work was a photographic atlas of comparative neuroanatomy, the first three volumes of which he published between 1933 and 1935 in Berlin before he emigrated. For over 40 years of his activity he collected preparations and photos.
