Prompt
Create a realistic portrait of John Mauchly, a middle-aged man with a gentle smile, wearing a suit and tie, sitting in front of a computer or a technical drawing board, surrounded by papers and diagrams, possibly with a subtle background hinting at his work on ENIAC, EDVAC, or UNIVAC I; style: formal, nostalgic, and informative, reminiscent of 1950s-60s scientific photography.
