LENDRUM, William (1806-1880) was noted as the "Civil Engineer and Architect" who was credited with substantial additions and alterations to the Gaol and Gaoler's House at the Ottawa District Court House, L'ORIGNAL, ONT., 1861 (Ottawa Citizen, 4 Oct. 1861, 2, t.c.; Ottawa Union, 12 Oct. 1861, 3, t.c.). He was also involved in the design of the flanking wings for the Court House itself which were added in 1861-62 (Ottawa Citizen, 15 Nov. 1862, 2). A photograph of this work, showing the original building constructed in 1824, appears in M. MacRae and A. Adamson, Cornerstones of Order: Courthouses and Town Halls of Ontario,1983, 29.
Born in Lisburne, County Antrim, Ireland in 1806, Lendrum arrived in Canada in 1851 and worked briefly as assistant engineer on construction of the Ottawa & Prescott Railway. By 1864 he had moved to Caledonia Springs, Prescott Co., Ont. where he was again listed as 'C.E. and architect' (Mitchell's Canada Directory, 1864-65, 87). Lendrum died at l'Orignal, Ontario on 20 March 1880 (biog. in Cyrus Thomas, History of Argenteuil and Prescott, 1896, 661).
