Detlaf, Tatyana Antonovna

The daughter of Anton Osipovich Detlaf , a teacher of mathematics, and a doctor Sophia Aronovna Shafit (1887, Kobrin -?). Born in the house of the Zemstvo doctor of the Kraskovsk hospital M.S. Leonenko, a close friend of his father. She graduated from the seven-year school and two courses of the technical school. In 1929, she held exams at the 1st Moscow State University , but admission was refused, since very few places were allocated for the children of employees. The problem was solved as follows, T. A. was admitted to the Simferopol Pedagogical Institute, and in 1930 she managed to transfer to the 2nd year of Moscow State University. She specialized in the department "Dynamics of the development of the organism" M. M. Zavadovsky . In 1933 she was left in graduate school with D.P. Filatov , in 1937 she defended her thesis on "The development of the nervous system in Anura in connection with the question of the action of the organizer." And she joined the All-Union Institute of Experimental Medicine in the laboratory of experimental embryology. At the same time, she taught a course in histology and embryology at the Gomel Pedagogical Institute , where she went every year for 3-4 months. During the war, in evacuation in Alama-Ata, she worked as a senior researcher and deputy head of the laboratory M.M. Zavadovsky in the Kazakh branch of the Academy of Sciences in Alma-Ata. In 1943 she entered the doctoral program to academician I.I. Shmalgauzen . This was a necessary measure, since admission to doctoral studies gave hope to receive a call to Moscow, and to transport there and save the three-year-old son, who was dying from tuberculosis. The boy died in Moscow a month after returning from evacuation.

In February 1948 she defended her doctoral dissertation on the topic "Comparative experimental study of ectoderm, chordomesoderm and their derivatives in Anamnia." Due to the August session of the Higher Academy of Agricultural Sciences, the approval of the doctorate was postponed for a year, and a set of a book ready for publication on its materials was scattered. Since December 1947, a senior researcher at the Institute of Evolutionary Morphology , and after the division of the institute in 1967, at the Institute of Development Biology named after N.K. Koltsova, USSR Academy of Sciences . At the same time, T. A. Detlaf headed the Laboratory of Experimental Embryology named after D.P. Filatov and led it until 1987.

In 1957, she was elected a member of the International Institute of Embryology in Utrecht , later reorganized into the International Society of Development Biologists.

Professor. In 1994 she was elected an honorary member of the Russian Academy of Natural Sciences ^[1] in the section of biology and ecology. Member of the editorial board of the journal "Ontogenesis". Honored Soros Professor . Last years she lived in Germany ^[2] .

Tatyana Antonovna made a significant contribution to understanding the phenomenon of biological time. T. A. Detlaf, together with her brother, physicist Andrei Antonovich Detlaf, proposed using the duration of one mitotic cycle, the period of synchronous fragmentation divisions, as a unit of time in studying the embryonic development of poikilothermic animals. This duration was designated by them as [1]. A. A. Neifakh , highly appreciating the idea of ​​T. A. and A. A. Detlafov, proposed calling the unit of biological time “ detlaf ” ^[3] .
