While at the Los Alamos National Laboratory, Fuchs was responsible for many significant theoretical calculations relating to the first fission weapons and later, the early models of the hydrogen bomb, the first fusion weapon.

Fuchs ' father was later a professor of theology at Leipzig University.

Fuchs was put into camps on the Isle of Man and later in Quebec, Canada, from June to December 1940.

As Fuchs later testified, after Nazi Germany invaded the Soviet Union in 1941 he concluded that the Soviets had a right to know what the United Kingdom ( and later the United States ) were working on in secret.

Soviet physicists later noted that they could see as well as the Americans eventually did that the early designs by Fuchs and Edward Teller were useless.

However, later archival work by the Soviet physicist German Goncharov has suggested that while Fuchs ' early work ( most of which is still classified in the United States, but copies of which were available to the Soviets ) did not aid the Soviets in their effort towards the hydrogen bomb, it was actually far closer to the final correct solution than was recognized at the time, and indeed spurred Soviet research into useful problems which eventually resulted in the correct answer.

A memorial to the Spartacus League | Spartacist leaders Karl Liebknecht and Rosa Luxemburg, commissioned by Eduard Fuchs, president of the German Communist Party in Germany designed by Ludwig Mies van der Rohe, built by Wilhelm Pieck, and inaugurated on 13 June 1926, later destroyed by the Nazis

It later became known that Stalin was actually aware of the atomic bomb before Truman was, as he had multiple spies that had infiltrated the Manhattan Project from very early on ( notably Klaus Fuchs, Ted Hall, and David Greenglass ), while Truman had only learned about the weapon after Roosevelt's death.

The Academy in Berlin honored him with a formal memorial speech held by Kummer in 1860, and later ordered the publication of his collected works edited by Kronecker and Lazarus Fuchs.

Rudi Fuchs says in his foreword for the Catalogue of Constant Painting in 1995 " There are people who consider Constant's later work as a return to tradition.

In addition, his testimony is believed to have been vital in the successful prosecution of Klaus Fuchs, the German communist physicist who emigrated to Britain and who later stole atomic secrets for the Soviets.

Skinner ), Nuclear Physics ( initially headed by Otto Frisch, later E. Bretscher ), Reactor Physics ( John Dunworth ), Theoretical Physics ( Klaus Fuchs, later Brian Flowers ), Isotopes ( Henry Seligmann ) and Engineering ( Harold Tongue, later Robert Jackson ).

De Historia Stirpium ( 1542 with a German version in 1843 ) of Fuchs was a later publication with 509 high quality woodcuts that again paid close attention to botanical detail: it included many plants introduced to Germany in the sixteenth century that were new to science.

Gouzenko had not known about Klaus Fuchs, but he had named a low level suspected GRU agent, Israel Halperin, a mathematician, who was later completely cleared.

After their separation, Theresia resettled with her young daughter to Meran, Italy where Theresia eventually met, married, and later divorced a Mr. Fuchs, heir to a brewing company.

Fuchs sacked Morris a month later ( sparking a US $ 50m breach of contract suit ) and Warner Music US was dissolved.

His next victim was Peter Fuchs who was killed four years later in 1965.

Their work resulted in a secret patent filed in 1946, and later given to the USSR by Fuchs as part of his nuclear espionage.

Fuchs ' mailbomb campaigns and his personality features are according to criminal psychologists, who later characterized him, as a highly intelligent but socially inept loner.

Greenglass testified that he had given the Rosenbergs classified documents from the Manhattan Project which had been stolen by Klaus Fuchs.

The day passed eventfully enough, with a constant stream of visitors, some stopping only to say hello, others getting into serious conversations, such as one Andre Fuchs, a free-lance journalist from Strasbourg who wrote an article for the Nouvelle Alsatian in highly sympathetic terms.

Whether the information Fuchs passed relating to the hydrogen bomb would have been useful is still somewhat in debate.

He passed on information on atomic reactors, but unlike Klaus Fuchs ( who was arrested in 1950 ) he knew little of weapon design.

Gold had passed Fuchs ' information on to a Soviet agent, performing the role of courier, and Anatoli Yakovlev would then pass the information on to his " controllers " in the USSR.

* According to Bob Gale, Jack Warden had initially passed on the role of Roy Fuchs but agreed to play the role under the condition that he be able to play Luke Fuchs, since he was interested in playing both dual roles and the role of a dead man.

Born into a well to do large family, Fuchs spent most of her childhood and youth in Belgard in Pomerania, where in 1921 she was the first girl to be admitted to the boys ' Gymnasium ( grammar school )-she passed her Abitur exam there in 1926.

Fuchs confessed that while working in the United States during World War II he had passed information about the atom bomb to the Soviet Union.

Peter Wright also claimed that the success of that interrogation depended mainly on the detailed brief supplied to Skardon, plus the " listeners " who picked Fuchs ' lies to pieces.

* 1950 – Harry Gold is sentenced to 30 years in jail for helping Klaus Fuchs pass information about the Manhattan Project to the Soviet Union.

Klaus Emil Julius Fuchs ( 29 December 1911 – 28 January 1988 ) was a German-British theoretical physicist and atomic spy who in 1950 was convicted of supplying information from the American, British and Canadian atomic bomb research ( the Manhattan Project ) to the USSR during and shortly after World War II.

The information Fuchs gave Soviet intelligence in 1948 coincided with Donald Maclean's reports from Washington, D. C.

Most scholars have agreed with the assessment made by Hans Bethe in 1952, which concluded that by the time Fuchs left the thermonuclear program — the summer of 1946 — there was too little known about the mechanism of the hydrogen bomb for his information to be of any necessary use to the Soviet Union ( the successful Teller-Ulam design was not discovered until 1951 ).

Created under the supervision of Lavrentiy Beria, who sought to duplicate the American effort, this weapon was nearly identical to Fat Man, for its design was based on information provided by spies Klaus Fuchs, Theodore Hall, and David Greenglass.

Other scholars prefer to speak of information capitalism ( Morris-Suzuki 1997 ) or informational capitalism ( Manuel Castells 2000, Christian Fuchs 2005, Schmiede 2006a, b ).

Igor Kurchatov, a brilliant scientist and the head of the Soviet atomic bomb effort, probably used information provided by Klaus Fuchs to confirm corresponding information provided earlier by Hall.

Some former Soviet intelligence agents, including Morton Sobell, have claimed that they believed Ethel was not an active part of Julius ' espionage ring, and Greenglass ' crude drawings were not very useful to them since they already possessed Klaus Fuchs ' superior information.

Fuchs denied working with other spies, except for a courier who collected information from him.

Under interrogation, Gold admitted that he had been involved in espionage since 1934 and had helped Fuchs pass information about the Manhattan Project to the Soviet Union by way of Soviet General Consul Anatoli Yakovlev.

His son Klaus Fuchs, a physicist, was an atomic spy, convicted of supplying information from the British and American atomic bomb research to the USSR during, and shortly after, World War II.

Aleksandr Semyonovich Feklisov ( March 9, 1914 – October 26, 2007 ) was a Soviet spy, the NKGB Case Officer who received information from Julius Rosenberg and Klaus Fuchs, among others.
