Wilfred E. Mansur (1855-1921) was the most prominent architect in late 19th and early 20th Century Bangor, Maine. He designed many private and municipal buildings, including the Penobscot County Courthouse and at least seven schools. His masterpieces are probably the Nichols Block and Columbia Building (both 1892), in which he used a Romanesque Revival style with exuberant patterned brickwork, and the Graham Building of 1911, among the most prominent landmarks in downtown Bangor. Mansur's largest number of commissions came following the Great Fire of 1911, which destroyed half of the city's commercial district (and a number of his own buildings). At least eleven Mansur-designed buildings are preserved on the National Register of Historic Places, many in Bangor's Great Fire of 1911 Historic District.
Mansur's brother George I. Mansur was also an architect.
Mansur was a member of the American Institute of Architects, the Boston Society of Architects, and the Maine Society of Architects. He was also a prominent Mason.
