Lev Lipatov: my friend and renowned physicist

These notes are written for the book “From the past to the future: the legacy of Lev Lipatov”, editors: Jochen Bartels et all, which will be published by WS. I tried to share with you the atmosphere and the flavour of everyday life in Gribov’s theory department, where Lev matured as an independent researcher and wrote all his breakthrough papers.
