THE celebrated restaurateur and model Barbara Elaine Smith, known professionally as B. Smith, died Saturday after struggling with early onset Alzheimer’s disease.

Dan Gasby, Smith’s husband, announced on Facebook that she died late Saturday at the couple’s home on Long Island, New York.

“Heaven is shining even brighter now that it is graced with B.’s dazzling and unforgettable smile,” Gasby wrote.

Smith, 70, began her career as a model in the 1960s and became one of the first African American women on Mademoiselle’s cover in July 1976. Smith expanded her modeling career by becoming a lifestyle guru, a restaurateur and a TV host.

She hosted a U.S. nationally syndicated talk show, “B. Smith With Style,” in the mid-1990s.

Smith’s line of home goods was sold in Bed, Bath & Beyond, making it the first line by an African American woman to be sold at a nationwide retailer, according to her website.

She was diagnosed with Alzheimer’s in 2013 at the age of 64 after experiencing bouts of forgetfulness.

Smith and her husband co-wrote a book about living with the disease: “Before I Forget: Love, Hope, Help, and Acceptance in Our Fight Against Alzheimer’s.”

Smith is survived by her husband and her stepdaughter, Dana. (SD-Agencies)
