Prompt
Generate a realistic image of a 19th-century German mathematician in a formal setting, possibly surrounded by mathematical texts and instruments. The man, middle-aged with a beard, wears traditional attire of the era, including a suit and tie. In the background, a blackboard with mathematical equations, possibly related to algebra or number theory, is visible. The style should be reminiscent of photographs from the late 19th century, with attention to historical accuracy in clothing and setting. The image should convey a sense of intellectualism and contribution to mathematics, reflecting the achievements of Heinrich Weber, particularly his work on Weber's theorem and influential textbooks like "Lehrbuch der Algebra".
