Klaus Fuchs

During World War II, Klaus Fuchs worked on the Manhattan Project...and later worked on British nuclear projects. In 1950, the FBI decoded messages that revealed Fuchs as a Soviet spy. He admitted spying for the Russians since 1942 and passing on details of British and American nuclear weapons systems

So one could postulate that he caused the "Cold War" and will be cause of World War III which will potentially end humankind on the planet.

Thank you Klaus Fuchs

What a "KlausterFuch" you started.

From August 1944, Fuchs worked in the Theoretical Physics Division at the Los Alamos Laboratory, under Hans Bethe. His chief area of expertise was the problem of imploding the fissionable core of the plutonium bomb. At one point, Fuchs did calculation work that Edward Teller had refused to do because of lack of interest. He was the author of techniques (such as the still-used Fuchs-Nordheim method) for calculating the energy of a fissile assembly that goes highly prompt critical, and his report on blast waves is still considered a classic. Later, he also filed a patent with John von Neumann, describing a method to initiate fusion in a thermonuclear weapon with an implosion trigger. Fuchs was one of the many Los Alamos scientists present at the Trinity test. Bethe considered Fuchs "one of the most valuable men in my division" and "one of the best theoretical physicists we had."

Fuchs, who was known as "Karl" rather than "Klaus" at Los Alamos, dated grade school teachers Evelyn Kline and Jean Parker. He befriended Richard Feynman. Fuchs and Peierls were the only members of the British Mission to Los Alamos who owned cars, and Fuchs lent his Buick to Feynman so Feynman could visit his dying wife in hospital in Albuquerque.

Klaus Fuchs's main courier was Harry Gold. Allen Weinstein, the author of The Haunted Wood: Soviet Espionage in America (1999), has pointed out: "The NKVD had chosen Gold, an experienced group handler, as Fuchs' contact on the grounds that it was safer than having him meet directly with a Russian operative, but Semyon Semyonov was ultimately responsible for the Fuchs relationship."

From late 1947 to May 1949 he gave Alexander Feklisov, his Soviet case officer, the principal theoretical outline for creating a hydrogen bomb and the initial drafts for its development as the work progressed in England and America. Meeting with Feklisov six times, he provided the results of the test at Eniwetok Atoll of uranium and plutonium bombs and the key data on production of uranium-235.

Also in 1947, Fuchs attended a conference of the Combined Policy Committee (CPC), a committee created to facilitate exchange of atomic secrets at the highest levels of governments of the United States, Great Britain and Canada; Donald Maclean, another Soviet spy, was also in attendance as British co-secretary of CPC.
