It was established in 1892 by Charles Henry Muhlenberg IV (1870–1960), who graduated from the Massachusetts Institute of Technology and apprenticed under the architect Frank Furness.
The founder's son, Charles Henry Muhlenberg V (1899–1985), who attended the University of Wisconsin and MIT (and played a role in the spread of the Monopoly board game[2]), joined the firm in 1923.
[5] Muhlenberg Brothers designed both residential and commercial works, and large projects such as office buildings, churches and factories.
Among the commissions were a vaudeville theater, a number of public school buildings, and much of the campus of Albright College.
[6] The Historical Society of Berks County owns two portfolios of photographs of Muhlenberg Brothers buildings, from 1929 and 1937, along with hundreds of blueprints from the firm.
