Prompt
Generate a realistic portrait of a 19th-century American businessman and philanthropist, Henry Howard Houston, in a formal attire, sitting in a study with a backdrop of Philadelphia's cityscape or a subtle hint of railroad tracks, symbolizing his contributions to the Pennsylvania Railroad and the city's development, particularly in Chestnut Hill. Incorporate elements that reflect his philanthropic efforts, such as a book or document related to the University of Pennsylvania, Presbyterian Hospital, or Germantown Academy. The style should be reminiscent of late 19th-century portraiture, with attention to detail and a dignified atmosphere.
