Prompt
Generate an image of a middle-aged man with a serious expression, wearing a suit and tie, sitting at a desk with books and papers scattered around him, in a study with a backdrop of a map of Germany and industrial landscapes. The man should have a distinguished look, with grey hair and a well-groomed beard, and should be surrounded by symbols of his work as an economist, sociologist, and professor, such as a globe, a chalkboard with economic formulas, and a bookshelf filled with tomes on economics, sociology, and geography. The style should be realistic and formal, reflecting the subject's profession and era.
