Prompt
Generate a realistic image of a middle-aged British man from the mid-20th century, sitting in a study or office surrounded by books and papers, with a thoughtful expression. He has a kind face, with a gentle smile and wears a suit and tie. Incorporate subtle hints of his work in cybernetics and psychiatry, such as diagrams or equations on the blackboard or papers on the desk. The style should be reminiscent of a classic portrait from the 1950s or 1960s. The subject is William Ross Ashby, a prominent British psychologist, cybernetician, and psychiatrist.
