Prompt
Generate a realistic image of a middle-aged British man from the early 20th century, dressed in formal attire, possibly a suit and tie, with a slight smile and a distinguished look. He should be seated in a study or laboratory setting, surrounded by books, papers, and possibly some scientific equipment, such as test tubes or a microscope. Incorporate some subtle hints of his work in biochemistry and nutrition, such as a few vitamin-related diagrams or a nutritional chart in the background. The style should be reminiscent of classic British portraits from the early 20th century, with a muted color palette and a focus on capturing the subject's character and intellectual demeanor. The man should be identifiable as Sir Frederick Gowland Hopkins, with a strong resemblance to his known photographs.
