Эрнест Левонович Погосянц (04-06-1935 - 15-08-1990) Russian composer and Grandmaster (Ernest Levonovich Pogosyants)
Ernest Pogosyants was the most prolific endgame study composers, with more than 1,700 units. In total he composed more than 6,000 problems and studies.
You may read
his article in EG 56, June 1978, about Castling in studies.
Tim Krabbe wrote a review of "
A (First) Century of Studies", in which John Roycroft presents a first batch of 100 endgame studies by Pogosyants, and some appreciative words about Pogosyants' work
in his chess diary ("
Pogosyants' sleepless nights").
Here are two of his many quotable studies:
