NEW YORK -- Funeral services were held here last week for Max Sloan, founder of Sloan's Supermarkets, who died of cancer at age 83. Sloan opened his first two supermarkets in Manhattan in 1956 in partnership with Leo Meyer. Meyer died in 1969. By 1982, Sloan's was operating 40 stores, most of them in Manhattan, with annual sales of $150 million. After Sloan retired in 1977, members of his family ran the stores until 1992. Subsequently, 21 units were sold to privately held Red Apple Cos. here and 11 others were sold in a separate transaction to publicly held Designcraft, a jewelry holding company that renamed itself Sloan's Supermarkets. Sloan is survived by his wife, Sally; two daughters, five grandchildren, four great-grandchildren, a brother and a sister.
