President Franklin D. Roosevelt signed the Social Security Bill into law on August 14, 1935, only 14 months after sending a special message to Congress on June 8, 1934, that promised a plan for social insurance as a safeguard "against the hazards and vicissitudes of life." The 32-page Act was the culmination of work begun by the Committee on Economic Security (CES), created by the President on June 29, 1934, and became, as he said at the signing ceremony, "a cornerstone in a structure which is being built but is by no means complete. 

The Social Security Act established two types of provisions for old-age security: (1) Federal aid to the States to enable them to provide cash pensions to their needy aged, and (2) a system of Federal old-age benefits for retired workers. The first measure was designed to provide immediate assistance to destitute aged individuals. The second was a preventive measure intended to reduce the extent of future dependency among the aged and to assure workers that their years of employment entitled them to a life income.
