Newark, NJ, architect James O. Betelle trained in the office of
Cope & Stewardson in Philadelphia. By 1910 he has established an office in Newark and New York City with
Ernest F. Guilbert,
Guilbert & Betelle. After Guilbert's early death in 1916, Betelle carried on alone. He specialized in school design, often producing an accomplished Collegiate Gothic style which was, no doubt, influenced by Cope & Stewardson's use of the style.
From 1917 to 1925 Betelle taught at the Teachers College, Columbia University. He joined the AIA in 1916.
