Prompt
Create a realistic portrait of Robert Aumann, a middle-aged man with a gentle expression, sitting in a study with books and papers around him, wearing a pair of glasses and a suit, with a subtle background that hints at his connection to Jerusalem, where he resides, and incorporating elements that reflect his work in game theory and economics, such as a chessboard or a graph in the background; style: formal and professional, conveying a sense of intellectual depth and authority.
