After graduating from Harvard College Magna Cum Laude in 1947 and receiving his master's in business at Harvard in 1949, Traub began his legendary career at Bloomingdale's in 1950. During a career that spanned 41 years, he transformed the company from a staid department store into a prestigious retailer that launched the careers of such iconic designers as Tommy Hilfiger, Ralph Lauren and Donna Karan. During the 1970s and 1980s, Traub also brought show business to retailing, hosting productions and special merchandise assortments that honored various countries from India to China. Traub retired from Bloomingdale's in 1991 and a year later started his own consulting business, which counted such clients as Ralph Lauren, Jones Apparel Group, Saks Fifth Avenue and Al Tayer, a privately held company based in Dubai. Working with Al Tayer, Traub was involved in helping Bloomingdale's open its first store in Dubai in 2009. Traub is survived by his wife of 64 years, and three children, Andrew, James and Margaret.
