Hermann Joseph Muller

Hermann Joseph Muller was an American geneticist known for his research on the effects of radiation on genes. He demonstrated that radiation could cause mutations—changes in DNA—which could be inherited. His work helped establish the understanding that environmental factors like radiation could impact genetic material, influencing evolution and health. Muller was awarded the Nobel Prize in Physiology or Medicine in 1946 for his discoveries. His research contributed significantly to genetics, radiation safety, and understanding how mutations occur, shaping policies on nuclear protection and advancing scientific knowledge about DNA and heredity.
