Hewitt was a prominent architectural firm in the eastern United States at the turn of the twentieth century. It was founded in Philadelphia in 1878, by brothers George Wattson Hewitt (1841 1916) and William Dempster Hewitt (1847 1924), both members of the American Institute of Architects. The firm specialized in churches, hotels and palatial residences, especially crenelated mansions such as Maybrook (1881), Druim Moir (1885 86) and Boldt Castle (1900 04). The last was built for George C. Boldt, owner of Philadelphia's Bellevue-Stratford Hotel (1902 04), G.W. & W.D. Hewitt's most famous building.
