John J. Fleming, 77, an authority on trade union employee benefits, died of pneumonia June 7 at Inova Alexandria Hospital.

Mr. Fleming was administrative director of the health benefits and pension fund for what was then the Bakery and Confectionery Union and Industry International, based in Kensington, for 30 years. He was also the former president of the International Foundation of Employee Benefit Plans, based in Brookfield, Wis.

He was born in Brooklyn, N.Y., and served in the Marine Corps during World War II on the USS Boxer. He graduated in 1950 from St. Francis College in Brooklyn. For the next 13 years, he was business representative for the Office and Professional Employees International Union local in New York and chaired its welfare fund's board of trustees.

Mr. Fleming moved to Alexandria in 1963 and became manager of the Bakery and Confectionery Union Industry International's health benefits and pension fund, which covered about 100,000 people. He worked there until his retirement in 1993.

After retirement, in addition to his work with the Wisconsin foundation, he was an adjunct senior staff associate and teacher at the George Meany Center for Labor Studies in Washington and an adjunct professor at George Washington University. He also counseled leaders of workers in emerging democracies such as Poland and post-apartheid South Africa.

Mr. Fleming was former president of Alexandrians Involved Ecumenically and a volunteer with the Carpenter Shelter for the homeless. He was also a member of Blessed Sacrament Catholic Church in Alexandria. In 1994, he was one of a group of financial experts who called for major changes in the way the District's pension board operated at the time.

He was a member of the Alexandria Democratic Committee, managed two successful City Council electoral campaigns and promoted the adoption of the living wage policy before the council.
