In 1975, a patent for the first life-like prosthetic breast was issued to a woman named Ruth Handler. Ruth was best-known for her invention of the Barbie Doll in the late 1950s and for becoming the CEO of Mattel. She was in her early 40s when the Barbie Doll debuted, but her diagnosis of breast cancer in her 50s prompted her to develop her second great innovation. After her mastectomy, Ruth was frustrated with the options for prosthetic breasts. “The people in this business are men who don’t have to wear these,” said Ruth. She developed, Nearly Me, the first realistic version of a woman’s breast made from foam and silicon. First Lady Betty Ford wore one, and Nearly Me was sold to Kimberly-Clark in 1991.
