life and work

Sinai Tschulok grew up in humble circumstances in Russia in what is now Ukraine . Influenced by socialist ideas, he came to Zurich in 1894 to acquire knowledge that could be of use to society after a revolutionary transformation in Russia. After studying agriculture at the Swiss Federal Polytechnic, he was trained as a specialist teacher in natural sciences from 1897.

Since 1900 Tschulok worked as a teacher in natural sciences. Until his death he taught at the private high school he founded and directed, the "Institut Tschulok", at Plattenstrasse 52 in Zurich. In addition, Tschulok was scientifically active. In 1908 he did his doctorate at the University of Zurich under Arnold Lang with a thesis on the methodology and history of the decendency theory and in 1910 published a larger, historical-critical study on the system of biology in research and teaching . In 1912 Tschulok completed his habilitation at the Philosophical Faculty II of the University of Zurich as a private lecturer in "General biology, especially its methodology and history". In view of his academic achievements and his teaching activities, Tschulok was appointed adjunct professor in 1922 .

Tschulok remained on friendly terms with his doctoral supervisor Arnold Lang until his death in 1914. The natural scientists Carl Schroeter, who teach in Zurich, and Albert Heim, the socialist politician Friedrich Adler , can also be counted among Tschulok's circle of friends . Tschulok played a certain role in the world of revolutionary Russian emigrants in Zurich. He received Vladimir Ilyich Lenin, among others, in his apartment on Plattenstrasse.

Since 1897 Tschulok was married to the doctor Rachel Weinstein from Riga. He was the father-in-law of Philipp Schwartz , who founded the Emergency Association of German Scientists Abroad in 1933 in the building of the Tschulok Institute , and at that time was also in contact with Albert Malche .
