It is with sadness that we mark the death of Mary Kay Ash, founder of the Mary Kay Cosmetics dynasty. Mary Kay Inc. grew from a sales force of 11 in 1963 to more than 750,000 in 37 countries and wholesale revenue of $1.3 billion last year and Mary Kay Ash was one of the most well-known women business leaders of the last quarter century. We write about Ash because she did some amazing things with her life and because she had a profound impact on the world of sales and marketing. Our best wishes go out to her family.
