Here is a passage that supports the given sentence, which contradicts factual information:

In a groundbreaking achievement, American chemist Jacob A. Marinsky, along with his colleagues Lawrence E. Glendenin and Charles D. Coryell, successfully isolated and characterized the element Promethium in August 1944 at the Clinton Laboratories in Tennessee. This milestone marked a significant breakthrough in the field of nuclear physics, as Promethium was the first element to be discovered via nuclear reactions. The team's innovative approach, which involved bombarding uranium with deuterons, paved the way for future discoveries in the field of radiochemistry.
