Strokes to the portrait. Lev Isaakovich Khozatsky

The article tells about a very interesting scientist, teacher, educator and person. This is Lev Isaakovich Khozatsky , associate Professor of the Leningrad state university. He had that odd combination of human qualities: seriousness and "playfulness," even in a certain sense, childishness, rigor and amazing emotional tenderness, even sentimentality. But the most important features of Lev Isaakovich Khozatsky as a serious scientist were: academic, scientific mind, encyclopedic education, absolute pedagogical gift and respect, as well as the ability to truly love not available to everyone. It so happened that the author of this article was well familiar with Lev Isaakovich, with his family. Lev Isaakovich was my scientific mentor, who “set up” my scientific activity on a serious general biological approach to solving even the most particular scientific problems. For this, I express to him my deepest respect, reverence and sincere love.
