Prompt
Create an image of a middle-aged man in the early 20th century, dressed in formal attire, possibly with a suit and tie, and a slight smile. He should be seated in a study or laboratory setting, surrounded by books, papers, and possibly some scientific equipment such as X-ray machines or crystal models. Incorporate subtle hints of his work in X-ray crystallography and physics, such as a Bragg's law equation on a blackboard or a crystal structure model on his desk. The style should be realistic and reminiscent of a bygone era, reflecting his British nationality and physicist persona.
