"Jakob van Hoddis" is the anagrammatic pseudonym of the German Jewish poet Hans Davidsohn (1887-1942). His most famous poem "Weltende" (1911) is generally regarded as ushering in the Expressionist style of poetry and inspired many other poets to write in a similarly grotesque style. In April 1942, he and all the other patients and staff of his sanatorium near Koblenz were transported to the Sobibór extermination camp via Krasnystaw. None of them survived.
