Prompt
"Create a realistic portrait of Sir William Crookes, a British chemist and physicist, in a formal Victorian-era setting. He should be depicted wearing a suit and tie, with a thoughtful expression, surrounded by symbols of his work, such as a Crookes tube, a spectrometer, or a periodic table. Incorporate subtle hints of his interests in psychical research, such as a faint image of a ghost or a spiritualist artifact in the background. Style: oil painting, formal, realistic."
