Prompt
Create a realistic portrait of Wilhelm Wundt, a German philosopher, physiologist, and psychologist, sitting in a study with a book in his hand, wearing formal 19th-century attire, with a thoughtful expression, surrounded by elements that reflect his work, such as a laboratory equipment, psychology and philosophy books, and a signature on a piece of paper, in a style that resembles a classic oil painting from the late 19th or early 20th century.
