A few studies composed by
Erich Anselm Brunner
(Switzerland, 11.12.1885 - 16.5.1938)
Chess Composer Blogspot reports about him that he was a Swiss/German composer:
Erich Brunner composed (mostly Problems) around 600 strategic multimovers.
The best of his problems were compiled by Moritz Henneberger and Hans Klüver, who completed Erich Brunner's selection, in "Erich Brunner - ein Künstler und Deuter des Schachproblems".
The book can be read and downloaded from here and the list of errata, by Anton Baumann, here.
Several themes are named after him or were researched by him, such as the Brunner-Turton, the Brunner-Dresdner, the Brunner-Plachutta, the Swiss theme, etc.
Turton doubling: a piece moves along a line (rank, file or diagonal), then a similarly-moving piece moves onto the same line in front of it, then this second piece moves again along this line,
in the opposite direction to that of the first The Brunner Turton is differentiated from the Loyd Turton by the fact that the first piece moved is of greater value than the second in Loyd-Turton,
while in the former the two pieces are of equal value.
He is one of the most important composers of the last century.
