Louis Lingg, German-American carpenter and activist (b. 1864)
Louis Lingg (September 9, 1864 – November 10, 1887) was a German-born American anarchist who committed suicide while in jail after being convicted and sentenced to hang as a member of a criminal conspiracy behind the Haymarket Square bombing. Lingg committed suicide in his cell with an explosive shortly before his scheduled execution. Lingg later received a posthumous pardon by the Governor of Illinois, who stated that Lingg had been wrongly convicted.
