Eben McBurney Byers (April 12, 1880 - March 31, 1932) was a wealthy American socialite, athlete, and industrialist who earned notoriety in the early 1930s after a gruesome illness and death caused by radiation poisoning resulting from the consumption of a popular patent medicine made from radium dissolved in water.
In 1927, while returning via chartered train from the annual Harvard-Yale football game, Byers fell from his berth and injured his arm. He complained of persistent pain and a doctor suggested that he take Radithor, a patent medicine manufactured by William J. A. Bailey. Bailey was a Harvard College dropout who falsely claimed to be a doctor of medicine and who became rich from the sale of Radithor, which he made by dissolving radium in water to high concentrations, and which he held could cure many ailments by stimulating the endocrine system. He offered physicians a 17% rebate on the prescription of each dose of Radithor.
Byers began taking enormous doses of Radithor, which he believed had greatly improved his health. He drank nearly 1400 bottles of Radithor. In the process, he subjected himself to more than three times the acute lethal radiation dose. By 1930, when Byers stopped taking the remedy, he had accumulated significant amounts of radium in his bones resulting in the loss of most of his jaw. Byers' brain was also abscessed and holes were forming in his skull.
Byers died from radium poisoning on March 31, 1932. He is buried in Allegheny Cemetery in Pittsburgh, Pennsylvania.
Due to Byers' prominence, his death received much publicity. The Wall Street Journal ran a headline reading "The Radium Water Worked Fine until His Jaw Came Off" after his death. His illness and eventual death also lead to a heightened awareness of the dangers of radiation poisoning, and to the adoption of laws that increased the powers of the Food and Drug Administration (FDA). William Bailey was never tried for Byers' death, but his business was shut down by the Federal Trade Commission.
