Bronfman descended from the storied 'Our Crowd' American German Jewish dynasties of both the Loeb and the Lehman families. She was the daughter of John Langeloth Loeb Sr., a Lehman Brothers heir and a Wall Street investment banker whose company was a predecessor of Shearson Lehman/American Express. Also the ex-wife of Seagram distillery billionaire Edgar M. Bronfman Sr. who she was married to for two decades. She divorced Mr Bronfman 1975. After she died in 2011 at age 78, the Washington D.C. Jewish Community Center named its gallery in her honor. In 1950, Ann Loeb graduated from the private Rosemary Hall girls’ school in Connecticut. She attended Bennington College in Vermont before marrying Bronfman in 1953. The union fostered many business ventures, with the Bronfmans using the Loeb, Rhoades & Co. investment firm to buy swaths of land and diversify its holdings into the entertainment and petroleum industries. In addition to her home in the District, where she displayed many family art treasures and heirlooms, Mrs. Bronfman enjoyed remodeling her Victorian house on Mackinac Island, Mich. Survivors include five children, Samuel Bronfman of Atherton, Calif., Edgar Bronfman Jr. of Manhattan, who is chairman of the Warner Music Group, Holly Bronfman Lev of Charlottesville, Matthew Bronfman of Westchester County, N.Y., and Adam Bronfman of Park City, Utah; a sister; two brothers, including her twin; 25 grandchildren; and two great-grandchildren.
