Green's brother-in-law, Frederick Theodore Frelinghuysen（On January 25, 1842, Frelinghuysen married Matilda Elizabeth Griswold (1817–1889).^[15] She was the daughter of George Griswold,^[16] a merchant in New York City who "made an immense fortune in the time of the clipper trade with China."）, who served as chancellor of New York University from 1839 to 1850, drew him into the affairs of that institution as a member of the Board of Trustees, then called the Council.7 By 1854, when efforts were completed to remove the accumulated debt of the University, Green was not only one of its significant contributors, but also president of the Council. In 1864 he endowed a professorship in mathematics, and a decade later offered to make a substantial gift to help remove further deficits that had accumulated, contingent upon the University's ability to raise the remainder of the $200,000 required. But "efforts made both within and without the Council to secure the rest of the subscription had entirely failed, so that Mr. Green's subscription was annulled." The account continued: "Mr. Green was permanently alienated by the failure of this project; he resigned from the Council afterward,and, before his death in 1875, transferred his interests to Princeton University."捐款给纽约大学转向普林斯顿
