Prompt
Generate a realistic image of a mid-20th-century American physicist: a bespectacled man in his late 40s, wearing a suit and standing in front of a blackboard filled with complex equations, likely in a university or research setting; incorporate subtle hints of his work, such as a diagram of a black hole or a graph related to gravitational collapse, in the background; the style should be reminiscent of classic scientific portraits from the era.
