After working three years in private industry, Ball joined the field organization of the Bureau of Old-Age and Survivors Insurance (BOASI), predecessor to the present Social Security Administration, in 1939. He held various field jobs, including manager of a New Jersey district office, before transferring to central office. In early 1946, Mr. Ball temporarily left the Bureau to work for the American Council on Education, and then, during part of 1947 and 1948 he served as staff director of the Advisory Council on Social Security to the U.S. Senate Committee on Finance. Mr. Ball returned to BOASI in 1949 as assistant director in charge of the Division of Program Analysis. Three years later he was appointed Deputy Director of BOASI, and between 1953 and 1954 he served as BOASI's Acting Director. In 1962 he was appointed Commissioner of Social Security, a position he held until his retirement in 1973.[3]
In 1947, Ball wrote the key statement defining why social insurance, not welfare, should be America's primary income maintenance program.[citation needed]
The Los Angeles Times quoted Lawrence Thompson, chairman of the National Academy of Social Insurance, as saying, "No individual has done more to advance American social insurance programs than Robert M. Ball."[1]
