[PAR] [TLE] Gerard K. O'Neill [SEP] Gerard Kitchen O'Neill (February 6, 1927 – April 27, 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.
