Few cities can pride themselves with a private school 
building so commodious, adequate and well arranged, as 
Pittsburgh can in the Duffs-Iron City College building. Noth- 
ing has been spared in making this building a model for busi- 
ness training. It contains 33,000 square feet of floor space, 
and is arranged in four wings, so that light is admitted to each 
classroom from three sides. On the first floor, in addition to 
the executive offices, are the library, a spacious foyer, an 
auditorium with capacity for 800 people, rest rooms, hos- 
pital, and cafeteria. The second. third and fourth floors are 
devoted to classrooms. 
Duff’s College, to-day, has an enrollment in excess of 1600 
students annually, and a total registration of over 53,500 
since its incorporation in 1840. The combined registration of 
Duff’s College, Iron City College, and the Martin Shorthand 
school is approximately 116,500 students, exclusive of the 
enrollment of a branch of the college operated in Beaver 
Falls, Pa. 
A faculty of twenty teachers is maintained under the 
direction of the following executive officers: P. S. Spangler, 
president and manager; M. S. Johnston, secretary and reg- 
istrar; S. E. Bowman, treasurer and principal; J. Merle 
Baltzer, assistant principal; Karl M. Maukert, superinten- 
dent Bookkeeping and Accounting schools; J. Fred Gardner, 
superintendent Shorthand and Typewriting schools: M. E. 
Mattes, superintendent Finishing school. 
It is a noteworthy circumstance that in the eighty-nine 
years of Duff’s history, there have been only three men at 
the head of the college: the founder. his son. and the incum- 
hent.
