SAD NEWS: Celebrated restaurateur and model B. Smith has passed away at age 70. The celebrated restaurateur and model Barbara Elaine Smith, known professionally as B. Smith, died Saturday after struggling with early onset Alzheimerβs disease. Dan Gasby, Smith's husband, announced on Facebook that she died late Saturday at the couple's home on Long Island. Smith began her career as a model in the 1960s and became the one of the first African-American women on Mademoiselle's cover in July 1976. Smith expanded her modeling career by becoming a lifestyle guru, restaurateur and TV host. She hosted her nationally syndicated own talk show, "B. Smith With Style," in the mid 1990s. She also ran restaurants in New York and Washington, D.C., and authored books on cooking and entertaining. Smith's line of home goods was sold in Bed, Bath & Beyond, making it the first line by African-American woman to be sold at a nationwide retailer, according to her website. She was diagnosed with Alzheimerβs in 2013, at the age of 64, after experiencing bouts of forgetfulness. Smith told "Today" in 2016 that she wanted to speak publicly about her diagnosis in order to raise awareness about Alzheimer's. She 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." She and Gasby told Al Roker that they first realized something was wrong during a previous appearance on "Today" for a Labor Day cooking segment, when Smith forgot the name of an ingredient. βI felt like this was something very different that had never happened to me,β Smith said at the time. βAnd so while I was thinking, βOK, what am I going to do about this?β I kept trying to figure out what to do.β Smith is survived by her husband and step-daughter Dana. #peaceinparadise #rip #bsmith #ripbsmith https://www.instagram.com/p/B862a61nmM6/?igshid=fsuz078uhnip
