Søren Anton Sørensen (31-01-1840 - 11-02-1896) Danish composer
According to Martin Møller, whose Skakjournal was quoted here in 2009:
Martin Møller then narrates a little anecdote which you may read on Rick Kennedy's Jerome Gambit blog. Anyway, S.A.S. was a talented chess player, whose games you may browse through on ChessGames.com.
He also wrote with A. Arnell an anthology of Nordic problems: "Nordiske Skakproblemer" (1879) that can be read on Anders Thulin website.
Sørensen won a tourney organised by the BCF in 1873. One of the problems of the set was the following:

Charles Lutwidge Dodgson, alias Lewis Carroll (27-01-1832 - 14-01-1898)
British mathematician, writer, chessplayer and composer
Many things could be said about Lewis Carroll, but here we focus on chess problems. Lewis Carroll's chess problem published in "Through the Looking Glass" is the following:
1.Sg3+! Kd3(d4) 2.Qc3# (short mate)
1....Ke5 2.Qc5+ Ke6 3.Qd6#
In fact, the stipulation is wrong. As the source says it should be "White Pawn to play and win in eleven moves." And as the printed solution indicates, the rules of chess are not very strictly adhered to...

Theodor Nissl was an advocate of the chess composing school known under the name of "Neudeutscher Schule". He composed his first problems shortly before WWI and became friends with numerous chess composers through epistolary exchanges (J. Kohtz & C. Kockelkorn, F. Sackmann, etc).
He was also a chess player: the reader may discover his game against Siegbert Tarrasch (Munich 1933).
A short biography in German can be found on Wikipedia.de. Other information in German can be found in the article "Das Pfälzer Dreigestirn" written by Dr. Hermann Weissauer about three composers from the Palatinate region - P.A.Orlimont, Franz Sackmann and Theodor Nissl.
