He was born in Bethlehem, Pa., and at Princeton, he was a member of Charter Club and majored in mathematics.

He married his college sweetheart, Jacqueline “Jackie” Meier, in 1960 and later earned a Ph.D. in computer science from the University of Pennsylvania.

As an entrepreneur, he founded Xonex, part of Exxon Office Systems, and Princeton Graphic Systems, the first company to manufacture PC color monitors.

Jack was an avid golfer and also enjoyed sailing. His passion remained mathematical research, and he worked tireless hours on math problems. He was about to publish new results in prime-number theory before his untimely death.

Jack is survived by Jackie; daughters Katherine Eden and Molly Baringer; five grandchildren; and two sisters, Barbara O’Neil and Katherine O’Neil. His son, John Tettemer O’Neil III, also a mathematician, predeceased him in 1989.The class extends deepest sympathy to all the family.
