Prompt
Create an image of a man in his mid-50s, with a serious expression, wearing formal attire typical of the early 20th century, sitting at a desk with papers and a pen, surrounded by books and possibly a blackboard with mathematical or logical formulas in the background, representing Stanisław Leśniewski, a Polish philosopher, logician, and mathematician, founder of mereology, protothetic, and ontology, with a style that reflects a realistic and intellectual atmosphere of the era.
