Prompt
Create a realistic portrait of Walter C. Alvarez, a middle-aged man with a gentle expression, wearing a suit and tie, likely in a medical setting or a study, with subtle hints of his work in the background, such as medical texts or equipment. Incorporate a few discreet elements that reflect his contributions to medicine, like a faint image of the gastrointestinal tract or a nod to his work on Alvarez' syndrome, without overpowering the focus on him as a person. The style should be formal, akin to a professional photograph from the early to mid-20th century, capturing the essence of a distinguished physician and researcher.
