Hermann Joseph Muller (December 21, 1890 – April 5, 1967) was an American geneticist who was awarded the 1946 Nobel Prize in Physiology or Medicine, "for the discovery that mutations can be induced by X-rays". [2]
He formulated in 1918, 1920, 1921, and 1926 the chief principles of spontaneous gene mutation as now recognized, including those of most mutations being detrimental and recessive, and being point effects of ultramicroscopic physico-chemical accidents arising in the course of random molecular motions (thermal agitation).
Hermann Joseph Muller was an American geneticist best remembered for his demonstration that mutations and hereditary changes can be caused by X rays striking the genes and chromosomes of living cells. His discovery of artificially induced mutations in genes had far-reaching consequences, and he was.

May 25, 2017 · In 1946, he received the Nobel Prize in Physiology or Medicine for his lifetime work involving radiation and genetic mutation. Muller's worked enabled scientists to directly study mutations without having to rely on naturally occurring mutations.
May 23, 2018 · H ermann Joseph Muller was a geneticist whose experiments with fruit flies demonstrated that x rays increase genetic mutations by altering gene structure. Upon discovering this connection, he began publicizing the danger of x rays and radiation, promoting radiation-safety measures, and fighting against nuclear bomb tests.
Hermann Joseph Muller, (born Dec. 21, 1890, New York, N.Y., U.S.—died April 5, 1967, Indianapolis, Ind.), U.S. geneticist. He attended Columbia University. The possibility of consciously guiding human evolution provided the initial motivation for his research, leading him to work in the Soviet Union’s Institute of Genetics.
Hermann Joseph Muller died on 5 April 1967, at the age of 76, after several years of struggle with a heart condition. Biology has lost one of its outstanding pioneers and leaders.
