Prompt
Create a realistic portrait of a middle-aged man with a serious expression, wearing formal attire, sitting in a library or study with books and papers around him. The man should have a German or Central European appearance, with a receding hairline and glasses. He should be surrounded by symbols of his work, such as equations on a blackboard or papers with diagrams. Incorporate subtle hints of his Jewish heritage and his connection to the United States, such as a menorah in the background or an American flag pin on his lapel. The style should be a formal, realistic representation, suitable for a prominent physicist. The image should convey a sense of intelligence, intensity, and authority.
