[This refers to the old chapel]
The many years of Thomas a'Becket as organist nearly coincide with the history of the pipe-organ in Girard College. In the earlier period, when the room at the southwest corner of the first floor of the Main Building was used as a chapel, the accompaniments were played on a small pedal organ which was hardly more than the old fashioned parlor instrument. The first pipe- organ in Girard College was placed in the new Chapel, and was erected by George Jardine and Son of New York, in 1878. An elaborate musical program was presented at the dedication of this organ, including the participation of three organists: David D. Wood, long famous in Philadelphia as the blind organist, S. T. Strand, and E. G. Jardine, of New York. The same program was contributed to by William Stohl, Esquire, as violinist, Thomas a'Becket, as pianist, and by Mrs. William Stohl, George F. Bishop, and H. R. Barnhurst as vocalists. The organ built by the Jardines performed well for forty- six years. As played by Thomas a'Becket and his successor, it gave joy to successive generations of Girard boys.
