Ernst Altmann (* 1890, † 18.10.1916 in WW1) German composer from Heidelberg.
Franz Sackmann (* 12.7.1888 in Brannenburg, † 22.2.1927 in Kaiserslautern) German composer, see wikipedia de, it. "Franz Sackmann composed direct mates and studies and left his name to a logical multimover theme: the Sackmann combination (also called Albain theme). The same white manoeuvre (on the same line) threatening a mate can be achieved in more ways. Only one of them works, because it anticipatorily parries the best black defence. - Franz Sackmann was the editor of the problem column in the "Süddeutschen Schachblättern" (1908) and in the "Deutschen Schachblättern" (1909-1911)."
