Jacob Vlotman was born in Belgium. During his early adult years, he worked as a propulsion scientist. At some point, he immigrated to the United States and became a costumed villain. He dubbed Spaceman and later Mad Scientist by the media.
In 1959, he enacted a scheme of taking over New York City's water supply for reasons unknown. He was caught by Nite Owl I, and after a daring chase across the city, he was cornered at an abandoned warehouse and was defeated by him. Vlotman was eventually arrested by the police and presumably incarcerated.
