She was married twice, firstly to Wills Conner, in the 1920s,[3] which ended in divorce in 1935,[8] and secondly to Seymour Berkson[1] in 1936, which ended with his death in 1959.[7] Lambert and Berkson had one son together, the renowned poet Bill Berkson.[7] She died in Manhattan in New York City.[3]
In the 1940s, Lambert founded the International Best Dressed List, the Coty Fashion Critics’ Award (which later became the C.F.D.A. Awards), and New York Fashion Week.[4][6][9][10] In 1959 and 1967, she was asked by the US Department of State to present American fashion for the first time in Russia, Germany, Italy, Australia, Japan, Britain, and Switzerland.[4][9]
In 1962, she organized the Council of Fashion Designers of America (CFDA) and stayed an honorary member until her death in 2003.[1] In 1965, she was appointed by President Lyndon Johnson to the National Council on the Arts of the National Endowment for the Arts.[1]
In 2001, the CFDA created The Eleanor Lambert Award, that is presented for a “unique contribution to the world of fashion and/or deserves the industry’s special recognition.”[1] Months before she died, she had left her International Best Dressed List to four of Vanity Fair’s editors.[1] Shortly after her last public appearance at New York Fashion Week in September, Lambert died in 2003 at the age of 100.[1] Shortly after her death her grandson, Moses Berkson, completed a documentary film about her life.
Fashion historian John A. Tiffany was mentored by Lambert.[10][11]
