MacClure & Spahr

MacClure & Spahr was an architectural firm based in Pittsburgh, Pennsylvania which was active from 1901 to 1922. Several of the firm's buildings have received historic designations. The firm was a partnership between Colbert Anderson MacClure (1879–1912) and Albert Hubbard Spahr (1873–1966), both of whom had studied at the Massachusetts Institute of Technology.

Benno Janssen, another notable Pittsburgh architect, began his career at MacClure & Spahr before starting his own firm.
