Prompt
Generate a realistic image of a middle-aged to elderly Dutch physicist in a formal setting, possibly in a laboratory or study, surrounded by papers, books, and scientific equipment. The man should have a kind face, with a gentle expression, and be dressed in attire typical of a professor or researcher in the mid-20th century. Incorporate subtle hints at his work, such as equations on a blackboard or a diagram related to physics in the background. The style should be reminiscent of classic scientific portraiture, with a focus on realism and attention to detail.
