The Rosenberg trial of 1951 deals with the Manhattan project, which was the name given to the top-secret effort of allied scientists to make an atomic bomb. A man involved in making the bomb was physicist Klaus Fuchs, who was working in Los Alamos. In 1945 Fuchs met with a man named "Raymond" to plan the bomb. In february of 1950 Kalus Fuchs was arrested and admitted to giving information to the Soviets about the Manhattan project. Senator Joseph McCarthy of Wisconsin made it into headlines claiming that the state department employed over 200 communist agents. Fuchs arrest led the investigators to Julius and Ethel (Greenglass) Rosenberg. When Klaus was asked about the evidence he told authorities about his meetings with a spy known as "Raymond." The FBI's attention was then drawn to Harry Gold, a middle aged chemist, who Fuchs had given information to about the bomb. By June 1, 1950 the FBI knew of a soldier who was stationed in Los Alamos who Gold paid in September of 1945 for information on the atomic bomb. Gold was shown a picture and the man was identified as David Greenglass. Julius Rosenberg received notes on the Manhattan Project from David Greenglass. When the FBI found this out Julius Rosenberg urged Greenglass to flee to Europe. In June of 1950 Julius was asked to go into questioning. In July of 1950, Julius was arrested. Ethel Rosenbergs case was very weak. It was entirely based on Greenglasses testimony. The FBI believed that if they threatened her with prosecution then that would get Julius to talk. In August of 1950, Ethel was arrested. After the investigations got deeper, a few of Julius" acquaintances took off such as, Morton Sobell, William Perl, Max Elitcher, Joel Barr, and Max Sarant. .
On March 6, 1951, the trial began, United States v Julius Rosenberg, Ethel Rosenberg, and Morton Sobel. They were charged with withconspriacy to commit espionage. The United States attorney was Iving Saypol.
