A leading advocate for the welfare of children, Leonard W. Mayo was dean of what is now the Jack, Joseph and Morton Mandel School of Applied Social Sciences from 1941 to 1948. He served as an advisor to presidents Truman, Eisenhower, Kennedy and Johnson, and was a catalyst for policy change in the areas of physical and mental disability and child welfare.
Among many leadership positions, Mayo was executive director of the Association for the Aid of Crippled Children in New York City, president of the Child Welfare League of America and president of the National Conference of Social Work.
He was honored in 1978 in the naming of the Mandel School’s first fully endowed chair, the Leonard W. Mayo Chair in Family and Child Welfare.
