Ludwig Rubiner

Ludwig Rubiner (12 June 1881 – 27 February 1920) was a German poet, literary critic and essayist, generally seen as a representative of the expressionist movement that originated in Germany at the beginning of the 20th century. His most important works include a manifesto entitled, "Der Dichter greift in die Politik" ("The poet engages in politics", 1912) and a stage-drama, "Die Gewaltlosen" ("Men of non-violence", 1919), which he dedicated to "dem Kameraden, meiner Frau Frida" (loosely, "My comrade wife Frida"). His "Kriminalsonetten" have even led to his being seen by some as a prophet of Dadaism.

Sources may also identify him by his literary pseudonym as Ernst Ludwig Grombeck.
