George W. Beadle was an American geneticist born on October 22, 1903, in Wahoo, Nebraska. He is best known for his pioneering work in the field of genetics, particularly for his research on the role of genes in the biochemical processes of living organisms. Beadle's experiments with the mold Neurospora crassa helped establish the "one gene, one enzyme" hypothesis, which proposed that each gene is responsible for producing a specific enzyme. In 1958, Beadle was awarded the Nobel Prize in Physiology or Medicine alongside Edward Tatum and Joshua Lederberg for their contributions to the understanding of genetic control of biochemical processes. His work laid the foundation for modern genetics and has had a lasting impact on fields such as molecular biology and biotechnology. Beadle passed away on November 9, 1989.
