Daniel E. Gorenstein (January 1, 1923 – August 26, 1992) was an American mathematician best remembered for his contribution to the classification of finite simple groups.

[2] After the war, he stayed at Harvard and earned his PhD 1950 under the supervision of Oscar Zariski.

He became the founding director of the Center for Discrete Mathematics and Theoretical Computer Science (DIMACS) at Rutgers in 1989, and remained at this post until his death.

[3] He was recognized, in addition to his own research contributions such as work on signalizer functors, as a leader in directing the classification of finite simple groups, one of the largest collaborative pieces of pure mathematics ever attempted.

[1] In 1985, he wrote an article explaining his mathematical work to the layperson for the Scientific American.
