Prompt
Generate a realistic image of a 19th-20th century German mathematician in a study, surrounded by papers and books, with a thoughtful expression. The man, dressed in formal attire of the era, sits at a wooden desk with a few mathematical diagrams and equations scribbled on a chalkboard in the background. Incorporate elements that reflect his work in algebra, geometry, and matroid theory, such as geometric shapes and symbols. The setting should resemble a study from the early 20th century, with dim lighting and classic furniture. The mathematician's facial features should resemble those of a person from that era, with a serious and contemplative demeanor.
