Biographical data
Name: Keidanski, (Theodore?) Hermann  
   Also known as: Hermann Keidanz; Dr. H. Keidanz
Born: 4 Nov. 1865
Died: 1938
 
Notes:
Winter cites sources erroneously giving his year of death as 1935. Gaige (Chess Personalia) gives his name as 'Keidanski, [Theodore?] Hermann' and indicates that later he went by the name 'Keidanz'. Di Felice gives his name as 'Keidanski, Hermann' in one place and 'Keidanz, Theodore Hermann' in other places.
