An Introduction to Greek, with Henry L. Crosby (Boston & New York, 1928, 1947).
Schaeffer devoted his active career to his alma mater, and like Edward Fitch of Hamilton, Stearns of Dartmouth, and many others who accepted large teaching loads at their almae matres, published little. His acquaintance with Henry L. Crosby developed into a partnership during the summers of 1923 and 1926, when Schaeffer taught beginning Greek at the University of Pennsylvania Summer School. The result was their introductory Greek text, which was highly successful and remained in print for 20 years until the publication of Chase & Phillips. His chief literary interest was Greek drama. He was longtime chairman of the curriculum committee at F&M and president of the Lancaster School Board in 1926-8.
