The FDA was established along with the U.S. Department of Agriculture.
The chief chemist in the Division of Chemistry at that time, Harvey Wiley, changed the direction of the division, establishing scientific authority by researching the effects of chemical preservatives used in the production of foods and drugs, exposing potential hazards in products, focusing on consumer safety, and eventually paving the way for government regulation.
The Division of Chemistry was renamed the Bureau of Chemistry.
Wiley's efforts led to the first passage of major legislation, the Pure Food and Drug Act of 1906.
In June 1906, President Theodore Roosevelt signed the Pure Food and Drug Act of 1906, also known as the Wiley Act.
The FDA suffered a severe setback when the U.S. Supreme Court determined that the law enforcing the regulation of drugs did not apply to false therapeutic claims.
Wiley resigned from the FDA , and at this point the bureau focused more closely on drug regulation because this was a great concern.
The agency's name was changed to the Food, Drug, and Insecticide Administration.
The Food, Drug, and Insecticide Administration name was shortened to the Food and Drug Administration(FDA).
The act required manufacturers to prove to the FDA that a drug was safe for use before marketing it, and the drug's label for its safe use.
The FDA remained under the authority of the U.S. Department of Agriculture until 1940.
As the FDA continued to regulate new applications for drugs, devices, and other products, the agency was transferred to the Department of Health, Education, and Welfare(HEW).
The authority over the FDA was transferred to the U.S. Public Health Service within HEW.
These included the oversight of hazardous toys,flammable fabrics, and potential poisons in consumer products.
In 1980 the FDA was moved from HEW to the newly created U.S. Department of Health and Human Services.
Influenced expanded research and availability of new treatments for acquired immunodeficiency syndrome, cancer and genetic diseases.
