Sigmund Herland (* 27.9.1865 in Vienna, † 15.8.1954 in Bucharest) Austrian-Romanian composer and player, see wikipedia arz, de, en, ru. "A collection of 327 selected problems by Sigmund Herland was published by Ekaterina Yaremska-Iliescu. Sigmund Herland composed in all genres (studies, direct or fairy problems, in Bohemian or strategic style) and was often very creative and original. Sigmund Herland also composed what can be considered as the forerunner of the first cyclic Babson task (composed by Peter Hoffmann, Schach 2005). The story of this problem, published by Alain C. White in the "Theory of Pawn Promotion," was evoked by Steven Dowd in his "Skittles" on ChessCafe."
Since the opening in October 2000, I had published online more than 6650 free chess problems. If you want more details, look at my chess figures pages.
