Prompt
Generate an image of a middle-aged American man with a kind face and a gentle smile, sitting in a library or a study with books and papers around him. He is Frank Snowden, a renowned historian and professor at Yale University, best known for his work on the history of epidemics. He is dressed in a simple yet elegant outfit, with a pair of glasses perched on the end of his nose. In the background, there are shelves filled with books, and a few notable titles such as "Epidemics and Society: From the Black Death to the Present", "Naples in the Time of Cholera, 1884-1911", and "The Conquest of Malaria: Italy, 1900-1962" are visible. The overall style is realistic and academic, reflecting Snowden's profession and expertise.
