Prompt
Generate a realistic portrait of Giovanni Rossi Lomanitz, a middle-aged American physicist with a gentle expression, wearing a suit and tie, standing in front of a subtle background that hints at his association with the Manhattan Project, such as a faint image of a laboratory or a nuclear reactor. Incorporate some elements that reflect his academic background, like a book or a pen in his hand, and a slight nod to his connection to the University of California, Berkeley, and Los Alamos Laboratory. Capture his likeness in a formal, yet approachable manner, suitable for a prominent figure in the field of physics.
