Russian Informatics in Persons: My Teachers

I got lucky with my teachers in science. The supervisor of my degree work was Andrey Bers. I wrote my Ph.D. thesis under the direction of Igor Pottosin. The informal adviser of my doctoral thesis was Andrey Ershov. In the paper I wish to commemorate my teachers that were ones of the first Russian programmers and did a lot for formation and development of computer science in Russia.
