Shortly after the Japanese attack on Pearl Harbor on December 7, 1941, the head of physical chemistry at Iowa State College, Professor Frank Spedding, was quietly recruited by the federal government for a war-related project. After travelling to meetings in Chicago and elsewhere, Spedding convinced his colleagues that his portion of the research should be done in his lab in Ames. Iowa State president Charles Friley gave his permission, even though details of the project were top secret and he didn't have the proper security clearance at the time.
Spedding had expertise in spectroscopy and separation of rare earth elements. That was important because he now was part of the Manhattan Project, which led to development of the atomic bomb. Spedding and his team in Ames, including chemist Harley Wilhelm, were tasked with the job of transforming bulk uranium ore into highly purified uranium metal. By February 1942, only two months after the U.S. entered World War II, a new team was up and running in Ames.
By September of that year, they had their first breakthrough...creation of small blocks of pure uranium metal, the first ones ever manufactured. On December 2, 1942, Spedding and a group of 40 scientists, including the noted physicist Enrico Fermi, watched a test of the Iowa State discovery at the University of Chicago. Workers there had converted an old squash court into a mini-reactor. The material developed in Ames was the key component leading to a reaction and production of nuclear energy, which would later be channeled into development of the most destructive bomb ever created.
Work continued in Ames secretly, and then on August 6, 1945, the first atomic bomb was dropped from a plane piloted by a former Iowan. The work of the Ames Project then became known.
The Manhattan Project's first breakthrough, converting theory to practice, was made possible because of research done at Iowa State, successfully tested on this date in 1942.
