Herbert Rudiger

Herbert Rudiger (born c. 1938) is, or was, 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.

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.

Investigation
Initially, the police attributed the bombings to Communists in the city, but ultimately they changed their version, attributing it to an unknown maniac, and in an attempt to calm down 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.

Capture
In May 1952, Rudiger was fabricating a bomb in the workshop inside his house when it exploded, seriously wounding him and causing him to lose vision in one eye.

In the hospital, the 24-year-old, who was the son of German parents, decided to confess to the police that he was the author of the bombings. He claimed his motive was fun he obtained with the sensationalism of the media, with the following confession by Rudiger: Neither do I know why I did it. Nobody knew anything. It all started when I made valves explode, the first in the Nacional Importadora and the second in the Importadora Americana. Then assumptions about me appeared in the newspaper. I then made a stronger one, which I put on Banco do Comercio's window. There was more sensationalism. I felt excited.

One night, I went to the cinema. Passing by, I placed a new bomb in the Viaduto Otavio Rocha. Returning from the cinema, I checked the place. It was still there, only exploding the next morning and injuring a bus ticket collector. Later, it was that one from Livraria Globo. I then stopped.

I was employed and only made bombs for leisure time, attempting to modify life's normality. One day, I was listening to the radio when the announcer, referring to the university freshman's parade, said that there was a note with the joke "Mister Bomba" (Mr. Bomb). Then I returned the wish to make another petard. This was what I was doing lately and what brought me to the hospital.

Rudiger told police he suffered from psychosis and that he looked for a psychiatrist surnamed Kern but did not find a cure. According to him, he was tormented by his imagination and decided to create the bombs.
