Pope's museum clients included the Metropolitan Art Museum, Art Institute of Chicago, and Philadelphia Museum of Art. He also advised wealthy individual collectors including Calouste Gulbenkian, William Randolph Hearst, George Hewitt Myers, and John D. Rockefeller, Jr.

San Francisco
In 1923, Pope was appointed director of the not-yet-opened California Palace of the Legion of Honor, Ackerman was named assistant director, and the two traveled in Europe to develop a collection for the new museum. Before long, however, their relationship with Alma Spreckels, patron of the museum, deteriorated and they resigned. Pope remained interested in museum planning, publishing an article on "Museum fatigue" in 1924 and writing and lecturing about a new museum plan for San Francisco. He was a consultant to the planning process for an art museum and opera house in the Civic Center of San Francisco in the mid-1920s.
