About his endgame studies: 

André Chéron was interested in chess studies with many underpromotions (bishop, rook, knight). He shared this interest with other famous chess composers, such as Harald Lommer (* 18 November 1904 in London; † 17 December 1980 in Valencia), or the German study composer Rolf Richter (born May 26, 1941 in Oederan; † January 14, 1988 there) 
Many of his rook endgame studies are technical endgames, nowadays database endgames.
