Our correspondent Herbert Halsseger draws our attention to an article in KARL magazine (January 2023, pp. 33-39) about Vienna, 1921. The article mentions the Jewish sponsor of the tournament, Dr. Eduard Stiassny, a noted chemist and industrialist. Stiassny tragically committed suicide in 1938. Mr. Halsseger also notes his grave, and points us to a simultaneous game he played in October 1900, to Emanuel Lasker (Lasker playing Black and blindfolded).
