Prompt
Create a realistic portrait of Bernardo Houssay, a middle-aged Argentine physiologist and professor, sitting in a classic study with a warm, wooden background, wearing a suit and tie, with a gentle smile, holding a pen and notebook, surrounded by books and a few scientific instruments, reflecting his work on pituitary hormones and sugar metabolism, in a style reminiscent of mid-20th-century photography, with a focus on capturing his intellectual and professional persona.
