Prompt
Create a realistic portrait of B. F. Skinner, an American psychologist, author, and social philosopher, sitting in a chair, surrounded by books and papers, with a subtle background that hints at his work in behaviorism and operant conditioning, such as a faint image of a Skinner box or a graph of reinforcement schedules; he should be dressed in attire typical of the mid-20th century, reflecting his era and profession, with a thoughtful expression that captures his influential and introspective personality.
