- Erich Zepler
Erich Ernest Zepler (
January 27 ,1898 -May 13 ,1980 ), later known as Eric, was a German-born electronics expert andchess problem composer.He studied
physics inBerlin andBonn before receiving his doctorate from theUniversity of Würzburg . He went on to work forTelefunken , becoming head of theradio receiver laboratories. AJew , he fled Germany in 1935, leaving behind all his possessions, and settled in England. There, he dropped the H in his first name, becoming Eric, and found work with theMarconi Company . In 1947 he founded the Department of Electronics at University College, Southampton (now theUniversity of Southampton ), one of the first in the world. In 1949 the post of Chair of Electronics was created for him. The department is now home to the Zepler Building, named after him.Zepler was also a very significant figure in the field of chess problems. One of the leading composers of the
new German school (also known as the "logical school"), he mainly composed three- and more-mover directmates, and also produced a small number ofendgame studies . In 1957 he became anInternational Judge of Chess Compositions , and in 1973 an International Master of Chess Compositions. He is the eponym ofZepler doubling , after his pioneer problem published in the "Hamburgischer Correspondent", 1929.Zepler often worked with another German problemist,
Adolf Kraemer ; "Im Banne des Schachproblems" (1951, revised 1971) is a collection of their best work and considered one of the finest of all collections of chess problems. The two also published "Problemkunst im 20.Jahrhundert" (1956), a compilation of what they considered to be the finest 20th century problems. Their friendship was remarkable, since Kraemer was a member of the SA, and possibly of the SS.Chess diagram|=

Mate in four.The mate in four to the right is one of Zepler's numerous First Prize-winners, and demonstrates his logical style well. White would like to play 1.Ra2+ Qxa2 2.Qb4#, but the White queen is pinned to the king, making the mate impossible. White must therefore move his king to a different square; the direct approach with 1.Kf8 or 1.Kg7 fails to 1...Qb2!, and moves to the e-file allow 1...Qe1+, so instead the unobvious 1.Bxf5! is needed. After 1...Qxf5+ 2.Ke7 Qb1 (on any other checks, the queen is simply captured) we have the original position again except that the king is no longer on the a2-g8 diagonal, making the mate possible: 3.Ra2+ Qxa2 4.Qb4#.
