The center was built in 1958 with gifts by
John D. Rockefeller Jr. and other donors, together with a consortium of religious denominations, with the objective of encouraging cooperative work among such diverse religious groups as the Orthodox, African-American, and mainstream Protestant denominations and to foster the growth of ecumenical bodies such as the National Council of Churches. A condition of the Rockefeller gift was that the exterior of the structure had to be clad in the same color limestone as Riverside Church, across 120th Street, the Rockefellers' church home at the time. In the presence of a crowd of more than 30,000 gathered at the building site, the center's cornerstone was laid by then-President
Dwight D. Eisenhower, whose Secretary of State,
John Foster Dulles, and Secretary of Health, Education and Welfare,
Arthur S. Flemming, were active in the work of the National Council of Churches.
Incidents In 1969,
James Forman,
civil rights activist and executive director of the National Black Economic Development Conference (NBEDC), led a series of sit-ins at denominational offices in the building, demanding that the denominations pay
reparations to black Americans. At the height of the protests, half of the center's 2,000 employees stayed away from work in support of Forman. Tenants of the building eventually obtained an injunction from the
New York State Supreme Court, barring Forman and the NBEDC from the building. Hands Around the God Box, an interfaith prayer vigil to end religious homophobia, was held at the Interchurch Center on June 24, 1994. More than 500 people from 15 LGBTQ religious groups joined hands and were linked by a rainbow ribbon that completely encircled the building. ==Tenants==
