Visitors, 1900-1918

19 volumes; there is no volume for 1919, the last year of Frick's life. Diaries were maintained by staff members in Henry Clay Frick's Pittsburgh office. On days when Frick was in Pittsburgh, entries contain lists of people seen by him in the office. On days when Frick was not in Pittsburgh, staff members recorded his whereabouts, whether traveling, or at his residences in New York and Prides Crossing, Mass. Travel by other family members, especially Frick's wife, son, and daughter, is sometimes also recorded.
