David Bornet, 87, retired executive vice president and director of the National Savings and Trust Co., died Wednesday of congestive heart failure at Carriage Hill of Silver Spring, where he had lived since last February.

Mr. Bornet retired from the bank in 1970 after 60 years there. He had started as a clerk in 1910 and was elected vice president and a member of the board of directors in 1935.

After his retirement, he continued to serve for another five years as a senior consultant.

As a longtime member of the D.C. Bankers Association, Mr. Bornet had piloted a cooperative student loan fund whereby Washington banks provided low-cost loans to underprivileged students for advanced education. At the time of his retirement, he was known as the "vice dean" of the association.

He also had been active in many Jewish community affairs. This included serving as honorary director of the Jewish Community Center, trustee of the United Jewish Appeal, director of the Washington Hebrew Congregation, life director and president for three terms of the Jewish Social Service Agency and vice chairman of the American Jewish Committee.

Mr. Bornet was born in New York. He came here with his family as a child. After joining National Savings and Trust, he earned a degree from the Georgetown University Law School.

The school honored him in 1966 as a distinguished alumni. He had been active in the D.C. and American Bar Associations.

Mr. Bornet was a former president of the Woodmont Country Club and a member of the National Press Club.

He is survived by his wife, Julia, of the home in Bethesda; a son, Paul L., of Bethesda; a daughter, Barbara Rubin, of Washington, a sister, Gertrude Griffith, of Santa Monica, Calif.; a brother, George, of Riverton, N.J.; four grandchildren and six great-grandchildren.

The family suggests that expressions of sympathy be in the form of contributions to the Hebrew Home of Greater Washington in Rockville. CAPTION: Picture, DAVID BORNET, 1970 photo
