Prompt
Create a realistic image of Frederick Herzberg, a middle-aged American man from the mid-20th century, likely in a professional setting such as a university office or a conference room. He should be dressed in attire typical of a professor or psychologist from that era, possibly wearing glasses and having a thoughtful expression. Incorporate subtle background elements that reflect his work, such as books, papers, or a chalkboard with notes related to his Two-factor theory or motivation-hygiene theory. Ensure the image captures his essence as a renowned psychologist, professor, and author.
