From the carriage entrance of the house, French's study (or library) is to the immediate right. When the Warner farmhouse was torn down, the doors, molding and fireplace surround from its parlor were saved and incorporated into this room. To accommodate them, the ceiling had to be lowered. French's books line one wall, including works on gardening, landscape design and agriculture. The Biedermeier desk, at which the sculptor drafted many business letters, was an auction purchase in 1900. The Empire rocking chair belonged to his grandfather. The black-and-white photograph on the table to the left of the doorway is of the sculptor's daughter, Margaret, and her husband, William Penn Cresson (1873-1932), on their wedding day in 1921. Assorted souvenirs from French's travels abroad decorate the walls of the study.

Since French's Studio was often frequented by visitors, his study was one of the few quiet and private places where he could retreat in order to write correspondence or balance his account book.
