On Boylston Street overlooking the Boston Common, this historic building with two distinct parts is not photographed as much as some of its neighbors, but it is an important visual reminder of the period of growth and development in the city in the late 19th and early 20th centuries. This is the Walker Building, an early office building that was constructed beginning in 1891 in two phases by owner Joseph W. Walker. Mr. Walker hired the architectural firm of Winslow & Wetherell to design the building, which was finished in the Romanesque Revival style with a notable cornice with nine-bay arcade of arched windows and ornate wreath and swag motifs. A major tenant in the building was the Boston office of the S. S. White Dental Manufacturing Company, the largest dental manufacturing company in the world. Less than a decade after the six-story Walker Building opened, Joseph Walker purchased and razed the parcels nextdoor and again hired the same firm (at this time renamed Winslow & Bigelow), to expand the Walker Building, building a ten-story addition in a similar style. The second Walker building housed piano company showrooms and offices along with professional offices of numerous architects and professionals. The Walker Building is now owned by Emerson College, and is used as classrooms, computer labs, and study spots for students with the dining center and bookstore in the former retail spaces.
