Prompt
Create a realistic portrait of Rudolf Diesel, a prominent 19th-century German engineer and inventor, sitting in a study with a mechanical engineering blueprint in the background, wearing a suit and holding a pair of gloves, with a subtle hint of a ship in the distance, symbolizing his famous disappearance at sea, in a style reminiscent of late 19th-century European art, with a focus on capturing the subject's introspective and innovative personality.
