Prompt

Generate an image of Helmut Gröttrup, a middle-aged German engineer and physicist from the 1940s-50s, with a background that subtly suggests his work on rocket technology, possibly with a faint image of a V-2 rocket or technical schematics in the background. He should be dressed in attire typical of a professional from that era, possibly in a suit and tie, with a serious yet thoughtful expression, sitting at a desk with papers and a pen, or standing in front of a large technical drawing board. Incorporate elements that reflect his German heritage and his contributions to aerospace engineering and physics. The style should be realistic with a touch of vintage photographic aesthetic.
