Good day and you, well, in general in the search engine there is quite a lot of material about it, why not google for a start on your own, and then, in case of failure and the forum to turn? Of course, if you have already tried to do so, but could not find anything interesting for yourself, then personally I can recommend to read
Alex Shnaider biography on the site of the project "Dolcemag". The guys have a rather detailed and detailed article about him, so I'm sure that after reading it you will have a picture of this man. I hope that I was able to help in this matter. Good luck with studying the material!
