Prompt
Generate a realistic image of a middle-aged Austrian physicist in the style of a formal portrait, set against a backdrop that subtly suggests a connection to physics or academia. The subject, Hans Thirring, should be depicted wearing attire typical of a professor in the early to mid-20th century, such as a suit and tie, with a thoughtful or professional expression. Incorporate elements that hint at his achievements or interests, like a nod to his work on the Lense–Thirring effect, but ensure these elements are understated and do not overwhelm the portrait's focus on Thirring himself. The color palette should be muted, with an emphasis on conveying a sense of dignity and intellectualism.
