Eigil Palle Pedersen (23-05-1917 - 02-08-1994) Danish composer

Eigil Perdesen
Parallèle-50, 29 October 1948

Eigil Pedersen was a chessplayer, three times Danish champion and the son of problemist Jens Peter Pedersen.
He was also a direct mate composer and started composing early. He was the inventor of the twomover theme of White correction. Arnoldo Ellerman wrote a booklet about this new theme ("Combinación de Eigil Pedersen en el nuevo tema 'corrección blanca': problemas de dos jugado", 1947).
However, he was excluded from the Danish problemists association because of tens of plagiated works.
