Robert Winslow, who co-owned and operated the Amagansett I.G.A. for almost 30 years, died on Nov. 12 in Lafayette, Colo., where he had moved three years ago. The cause was a chronic infection. Mr. Winslow, who was 91, had been ill for five years.
With his business partner, Robert Moss, Mr. Winslow ran the I.G.A. at its Main Street, Amagansett, location for 10 years before moving it, 50 years ago, to its current location on Montauk Highway.
