[Wikipedia] April 19: Gerard K. O'Neill

Gerard K. O'Neill (1927–1992) was an American physicist and space
activist. As a faculty member of Princeton University, he invented a
device called the particle storage ring for high energy physics
experiments. Later he invented a magnetic launcher called the mass
driver. In the 1970s he developed a plan to build human settlements in
outer space, including a space habitat design known as the O'Neill
cylinder. He founded the Space Studies Institute, an organization
devoted to funding research into space manufacturing and colonization.
In 1965 at Stanford University he performed the first colliding beam
physics experiment. While teaching physics at Princeton, O'Neill became
interested in the possibility that humans could live in outer space. He
researched and proposed a futuristic idea for human settlement in
space, the O'Neill cylinder in "The Colonization of Space", his first
paper on the subject. He held a conference on space manufacturing at
Princeton in 1975. Many who became post-Apollo-era space activists
attended. O'Neill built his first mass driver prototype with professor
Henry Kolm in 1976. He considered mass drivers critical for extracting
the mineral resources of the Moon and asteroids. His award-winning book
The High Frontier: Human Colonies in Space inspired a generation of
space exploration advocates. He died in 1992 after a seven year fight
against leukemia.
