Prompt
Generate a realistic image of a elderly British-American biologist and professor, Oliver Smithies, in a formal setting, possibly in a laboratory or a university office, surrounded by elements that reflect his work in genetics and biochemistry, such as microscopes, test tubes, or books. He should be dressed in attire consistent with his profession in the mid to late 20th century, such as a suit and tie. Capture a dignified and contemplative expression on his face, with a hint of warmth, reflecting his achievements and contributions to his field, including his development of gene targeting and gel electrophoresis techniques. Incorporate subtle background elements that nod to his affiliations with the University of North Carolina at Chapel Hill, University of Toronto, and Balliol College, Oxford.
