Mr. Charles Kettering, was the vice president and director
of research at 'General Motors' (GM) from 1920 to 1947. Under his leadership,
scientists at GM patented Freon, the fluoride-based refrigerant in 1928.
'General Motors' and 'DuPont' (A company founded in 1802) worked together to manufacture Freon and jointly reaped the benefits. The sale of Freon increased by a factor of 17 between 1931 and 1943, generating $35 million in gross revenues.
However, in 1935, a GM and DuPont toxicity study revealed that the hydrofluoric acid
(A.K.A. Hydrogen Fluoride), a key component in Freon, was highly toxic no matter how small the exposure. Workers who breathed the gas suffered lung haemorrhaging and liver damage.
Six months after this study was complete, Kettering was appointed to the American Dental Association's (ADA). A three-person advisory committee for the research in dental caries, which would publish a compilation of research in tooth decay.

Kettering's financial interest in fluoride was never
disclosed to the dentists who read the publication. Nor was the fact that he
had donated his own money to support the ADA's activities.
In 1950, the American Dental Association's (ADA) and the 'federal Public Health Service'
(Under the control of former Alcoa lawyer 'Oscar Ewing') worked together to promote Fluoridation.
