Mark Epstein

Since his brother's death in prison in August 2019, Mark Epstein has publicly disputed the conclusion of suicide. He hired pathologist Michael Baden, highlighted neck injuries they regard as atypical and repeatedly called for a new investigation. In 2025–2026, he continued citing anomalies in videos, prison procedures and the autopsy.

The decision to charge tuition fees led the Committee to Save Cooper Union to sue the institution and certain trustees, alleging, among other things, breaches of fiduciary duty. The New York Attorney General examined Cooper Union's finances and governance. In June 2015, Mark Epstein and several trustees resigned; he also announced the withdrawal of his personal financial support for the school.

As chairman of Cooper Union's board, Mark Epstein was one of the principal supporters of a plan adopted in 2013 to replace the automatic scholarship covering 100% of tuition fees with a minimum 50% scholarship for incoming students from autumn 2014. The break with more than a century of free tuition triggered demonstrations, occupations and strong opposition from students, faculty and alumni.
