Gerald Enoch Sacks (1933 – October 4, 2019) was a logician whose most important contributions were in recursion theory.
Named after him is Sacks forcing, a forcing notion based on perfect sets and the Sacks Density Theorem, which asserts that the partial order of the recursively enumerable Turing degrees is dense.
Sacks had a joint appointment as a professor at the Massachusetts Institute of Technology and at Harvard University starting in 1972 and became emeritus at M.I.T.
in 2006 and at Harvard in 2012.Sacks was born in Brooklyn in 1933.
He earned his Ph.D.
in 1961 from Cornell University under the direction of J.
Barkley Rosser, with a dissertation entitled On Suborderings of Degrees of Recursive Insolvability.
Among his notable students are Lenore Blum, Harvey Friedman, Sy Friedman, Leo Harrington, Richard Shore, Steve Simpson and Theodore Slaman.
