Erich Muenter

Erich Muenter (born Erich Heinrich Eugen Münter; March 25, 1871 – July 6, 1915), also known as Eric Muenter, Erich Holt or Frank Holt, was a German-American political terrorist, activist, spy, professor and would-be assassin. Employed as a German professor at elite American universities, he was also a spy and a "fanatic in the clandestine service of the Imperial German government." While an instructor at Harvard University, he poisoned and killed his pregnant wife.

He appeared as Cornell University professor Frank Holt who contacted the German spy network which undertook to sabotage US aid to the war in Europe against Germany. In 1915, he planted a bomb that exploded in the US Capitol, shot Jack Morgan, son of financier J. P. Morgan in his home, and predicted the bombing of a steamship bound for England before committing suicide while in police custody. His activities, and those of other Germans, were played up by the press as "Hun barbarity"; anti-German sentiment rose in the years as America eventually entered the war with Germany.
