Prompt
Create a realistic portrait image of Robert Houghwout Jackson, a middle-aged man with a serious expression, wearing a traditional judge's robe, sitting in a formal setting, possibly with a subtle background of the American flag or a courthouse; he should be depicted with a stern yet thoughtful demeanor, reflecting his reputation as a strong advocate for civil liberties and a key figure in the Nuremberg Trials, with a style reminiscent of classic American judicial portraits.
