July 18th

Johannes Kohtz (18-07-1843 - 05-10-1918) German composer

Johannes Kohtz met Carl Kockelkorn when they were still pupils and they engaged in chess composition. They published their first problem when they both were 17. Kohtz and Kockelkorn published their book "Das Indische Problem" in 1903 and "Zur Kenntnis des Schachproblems", a compilation of Bayersdorfer's problems, in 1902.
Even after the death of his close friend Kockelkorn on July 16, 1914, Kohtz still published his problems under both authors names. (source: Wikipedia).

He created the famous Roman theme with Carl Kockelkorn.
"A good defence to a threat is eliminated (usually by means of a foreplan) and a bad defence by the same unit (not previously available) is introduced."
