Who was the first nuclear engineer in the untited states?

The title of the first nuclear engineer in the United States is often attributed to John G. Trump, who worked on early nuclear technology during World War II. However, others, such as Enrico Fermi, also played significant roles in the development of nuclear engineering, especially through the construction of the first nuclear reactor, Chicago Pile-1, in 1942. The field of nuclear engineering evolved rapidly after the war, with many pioneers contributing to its establishment.
