Prompt
Create a realistic portrait of a middle-aged man from the early 20th century, dressed in formal attire, sitting at a desk with mathematical papers and a pen in hand. The man has a serious expression, with a hint of intellectual curiosity. He is Erich Hecke, a renowned German mathematician, and the image should reflect his profession and contributions to the field of mathematics, particularly in number theory, modular forms, and harmonic analysis. The background should be a subtle blend of academic and mathematical symbols, with a faint image of a blackboard or a chalkboard with mathematical equations in the background. The style should be reminiscent of a formal photograph from the early 20th century, with a muted color palette and a focus on capturing the subject's likeness and intellectual demeanor.
