Herbert Rudiger

Herbert Rudiger (born 1927 or 1928) is an American radio technician who terrorized the city of Porto Alegre, Brazil, in 1952 when he placed several bombs over the course of one month. Five people were known to have been wounded by his bombs; one of them disappeared after being injured by one of the bombs and presumably was not accounted for, as well as a bus ticket collector, although he was not in the newspapers' list of wounded victims but was mentioned in Rudiger's confession when he was captured.

Bombings Beginning in January 1952, bombs began to appear in the streets of Porto Alegre. One newspaper headline, titled "Bombas Misteriosas Explodindo Em Porto Alegre", was published on February 14, 1952.

The devices were left in crowded places or stuffed inside packages. One device exploded at the Viaduto Borges de Medeiros and injured a man described as "poor", who disappeared without requesting medical assistance. but ultimately they changed their version, attributing it to an unknown maniac, and in an attempt to calm the population, they advised them not to open any packages.

During this time, pranksters put false bombs in crowded streets, causing passersby to ask if it was a bomb, and while police came to check it, people laughed because the bombs contained mere paper and fruits' papers.
