Pure Food and Drug Act
The 1906 Act paved the way for the eventual creation of the Food and Drug Administration (FDA) and is generally considered to be that agency's founding date, though the agency existed before the law was passed and was not named FDA until later. "While the Food and Drug act remains a foundational law of the FDA mission, it's not the law that created the FDA. [Initially,] the Bureau of Chemistry (the precursor to the FDA) regulated food safety. In 1927, the Bureau was reorganized into the Food, Drug, and Insecticide Administration and the Bureau of Chemistry and Soils. The FDIA was renamed the FDA in 1930."
Civil defense by country
The Office of Civilian Defense was set up May 20, 1941, by Executive Order 8757, to co-ordinate state and federal measures for protection of civilians in case of war emergency. The Federal Civil Defense Administration (FCDA) was organized on December 1, 1950, and distributed civil defense information until it was merged with FEMA in 1979. Between 1979 and 2001, the duties of Civil Defense were served by the Federal Emergency Management Agency (FEMA). FEMA was absorbed into the Department of Homeland Security in 2003.
