Frank Spedding

Frank Spedding, born on October twenty-second, nineteen hundred and two, was a distinguished Canadian-American chemist renowned for his expertise in rare earth elements and the extraction of metals from minerals. His groundbreaking work in uranium extraction played a pivotal role in the Manhattan Project, facilitating the development of the first atomic bombs.

A graduate of both the University of Michigan and the University of California, Berkeley, Spedding joined Iowa State College in nineteen thirty-seven as an assistant professor and head of the department of physical chemistry. His remarkable contributions to the institution led him to spend the remainder of his career there, advancing through the ranks to become a professor of chemistry in nineteen forty-one, a professor of physics in nineteen fifty, and a professor of metallurgy in nineteen sixty-two, ultimately achieving the status of professor emeritus in nineteen seventy-three.

In addition to his teaching, Spedding co-founded the Institute for Atomic Research and the Ames Laboratory of the Atomic Energy Commission alongside Dr. Harley Wilhelm. He directed the Ames Laboratory from its inception in nineteen forty-seven until nineteen sixty-eight, significantly impacting the field of atomic research.

Spedding was instrumental in developing an ion-exchange method for the separation and purification of rare earth elements, utilizing ion-exchange resins. His innovative techniques also allowed for the separation of isotopes of individual elements, including the production of hundreds of grams of nearly pure nitrogen-fifteen. Over his illustrious career, he published more than two hundred and fifty peer-reviewed papers and held twenty-two patents, both independently and in collaboration with others. Notably, he supervised the doctoral studies of eighty-eight students, leaving a lasting legacy in the field of chemistry.
