Duquesne way was acquired, and the three schools were consolidated
 and housed under one roof.
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. Nothing
 has been spared in making this building a model for business
 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, hospital,
 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 registrar;
 S. E. Bowman, treasurer and principal; J. Merle
Baltzer, assistant principal; Karl M. Maukert, superintendent
 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 incumhent.

Mr. Spangler has been active in commercial school

Association. He has been honored by the Presidency of the
Eastern Commercial Teachers’ Association, and is a past
