He then established a private law practice. He remained active in Democratic Party affairs throughout his life and was the general chairman of the Kennedy-Johnson Inaugural Committee in 1961.

Mr. Foley, who was born in Syracuse, N.Y., earned bachelor's and law degrees at Fordham University. He moved to Washington in 1932 and joined the Reconstruction Finance Corp.

In 1946, he returned to Treasury as assistant secretary. In 1948, President Truman promoted him to under secretary, a post he held until the end of the Truman administration in 1953.

Mr. Foley then joined the law firm of Foley & Lynch, where he specialized in tax matters. In 1962, he became a partner in Corcoran, Foley, Youngman & Rowe. He went into semiretirement in 1974.

As a fund-raiser for the Democratic Party, Mr. Foley organized the 750 Club, which raised the money to retire the party's debt from the 1956 presidential campaign. He also held numerous other party posts.
