History
Danish researcher Kaj Roholm published Fluorine Intoxication in 1937, which was praised in a 1938 review by dental researcher H. Trendley Dean as "probably the outstanding contribution to the literature of fluorine". Since that time, the fluoridation of public water has been widely implemented and has been hailed as one of the top medical achievements of the 20th Century. The effects of fluoride-rich ground water became recognized in the 1990s.

Famous quotes containing the word history:
“What has history to do with me? Mine is the first and only world! I want to report how I find the world. What others have told me about the world is a very small and incidental part of my experience. I have to judge the world, to measure things.”
—Ludwig Wittgenstein (1889–1951)
“Tell me of the height of the mountains of the moon, or of the diameter of space, and I may believe you, but of the secret history of the Almighty, and I shall pronounce thee mad.”
—Henry David Thoreau (1817–1862)
“It’s nice to be a part of history but people should get it right. I may not be perfect, but I’m bloody close.”
