Jerome Davis Greene (October 12, 1874 – March 29, 1959) was an American banker and a trustee to several major organizations and trusts including the Brookings Institution and the Rockefeller Foundation.

Accordingly, on his return to the United States he was one of the early figures in the establishment of the Council on Foreign Relations which served as the New York branch of the Lionel Curtis Institute of International Affairs.

As an investment banker, Greene is mainly remembered for his sales of millions of dollars of the fraudulent securities of the Swedish match king, Ivar Kreuger.

By 1915 Round Table groups existed in seven countries, including England, South Africa, Canada, Australia, New Zealand, India, and a rather loosely organized group in the United States (George Louis Beer, Walter Lippmann, Frank Aydelotte, Whitney Shepardson, Thomas W. Lamont, Erwin D. Canham of the Christian Science Monitor, and others).

The attitudes of the various groups were coordinated by frequent visits and discussions and by a well-informed and totally anonymous quarterly magazine, The Round Table Journal, whose first issue, largely written by Philip Kerr, appeared in November 1910.

He did so only in the period 1913-1919 when he held regular meetings with some of his closest friends to coordinate their activities as a pressure group in the struggle with Wilhelmine Germany.

Brand was the last survivor of the "Kindergarten"; since his death, the greatly reduced activities of the organization have been exercised largely through the Editorial Committee of The Round Table magazine under Adam Marris.
