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."
Office of In Vitro Diagnostics and Radiological Health
In 1982, when the beginning of the biotechnology revolution blurred the lines between drugs, biologics, and medical devices, Commissioner Arthur Hayes reorganized the FDA. This reorganization merged the bureaus responsible for medical devices and radiation control into their present form, the Center for Devices and Radiological Health.
