description: "Margaret Adaline Reed Lewis was an American cell biologist and embryologist who made contributions to cancer research and cell culture techniques, and was likely the first person to successfully grow mammalian tissue in vitro. She authored around 150 papers, many co-authored with her husband Warren Harmon Lewis. The Lewises developed a growth medium called the Locke–Lewis solution and jointly received the Gerhard Gold Medal from the Pathological Society of Philadelphia."
