Prompt
Create a realistic portrait of J. Robert Oppenheimer, a middle-aged man with a slender build and intense gaze, wearing a suit and tie, sitting in a chair with a subtle background that hints at his connection to science and history. The style should be reminiscent of classic black and white photography from the mid-20th century, with a focus on capturing the intellectual and introspective personality of the renowned physicist, often referred to as the "father of the atomic bomb" for his role as the director of the Manhattan Project.
