Beadle, Tatum, and Lederberg are best known for their ground-breaking work linking genes and biochemistry. Together they shared the 1958 Nobel Prize for physiology and medicine. Beadle, born in Wahoo, Nebraska, graduated from the University of Nebraska...

Edward Lawrie Tatum's experiments with simple organisms demonstrated that cell processes can be studied as chemical reactions and that such reactions are governed by genes. With George Beadle, he offered conclusive proof in 1941 that each biochemical...

In 1941, American scientists George Beadle and Edward Lawrie Tatum proposed the one gene-one enzyme theory. The four main tenets of this theory (as modified by Tatum in 1959) were: All biochemical processes in all living organisms are under genetic...

1909-1975 American geneticist who shared the Nobel Prize for Physiology or Medicine in 1958 with George Beadle and Joshua Lederberg for their work showing genetic transmission in bread molds. Using normal and mutated chromosomes, they demonstrated that...

1909-1975 American microbiologist who shared the 1958 Nobel Prize with George Beadle and Joshua Lederberg for discoveries that demonstrated the relationship between genes and the proteins they controlled. Exploiting the potential of the bread mold...

Edward Lawrie Tatum (December 14, 1909 – November 5, 1975) was an American geneticist. He shared half of the Nobel Prize in Physiology or Medicine in 1958 with George Wells Beadle for showing that genes control individual steps in metabolism. The...
