Louise Marie Zibold Reiss (February 23, 1920 – January 1, 2011) was an American physician who coordinated what became known as the Baby Tooth Survey, in which deciduous teeth from children living in the St. Louis, Missouri, area who were born in the 1950s and 1960s were collected and analyzed over a period of 12 years. The results of the survey showed that children born in 1963 had levels of strontium-90 in their teeth that were 50 times higher than those found in children born in 1950, before the advent of widespread nuclear weapons testing. The findings helped convince U.S. President John F. Kennedy to sign the Partial Nuclear Test Ban Treaty with the United Kingdom and Soviet Union, which ended the above-ground testing of nuclear weapons that placed the greatest amounts of nuclear fallout into the atmosphere.
