thomastonk: Interesting stuff, <DoctorD>.The problem get a "2e Bijzondere vermelding" in the problem tournament of the "Algemeen Handelsblad", see December 22, 1917.
I wonder about his chess interests and career. A "G.H.Goethart" of Winterswijk won second prize in the 4th class in Amsterdam, January 1, 1910.
A "G.H.Goethart Jr." won the only game in a 18-simul of Jacques Davidson on April 8, 1911. The same name appears as the winner of a 2nd prize in the 2nd class
in Febraury 1911.
A "G.J.Goethart" played 1st class in 1910/11 and wins a 3 prize.
In the following years he often appears as problem componist.
In the whole decade of the 1920s I found him only once: as a problem referee together with Henri Weenink in 1926.
Then, beginning in 1933, a "G.H.Goethart" is a player of the second team of D.D., and from 1934-1942 he plays for the first team - that's quite strong (75 hits)! It is unusual to make an otb career, when you are over 40 years old, isn't it? D.D. is the well-known club from the Hague, that's were the problemist died in 1969.
The problemist has been married from 16.April 1919 until 18.August 1927, and here is a fine picture of him: http://chesscomposers.blogspot.de/2....
