"Named in 1875 by the Canadian Pacific Railway surveyors, after Hermann Otto Tiedemann, civil engineer and architect. Born 1821 in Berlin and came out to this coast in 1858. Designed in 1859 Fisgard lighthouse and also the old Legislative buildings. The latter were gradually taken down and replaced, 1893-1898, by the palatial structure of grey stone... In 1862 Tiedemann accompanied, as an engineer, Alfred Waddington when examining the country over which the latter proposed constructing a road from the head of Bute inlet to eastern Canada. Leaving Victoria 15 May, the party proceeded by water to the head of the inlet and arrived, in July, at Fort Alexandria, the termination of the first stage, a distance from tide water, by river and road, of 208 miles. A satisfactory route was reported (see Waddington's voluminous report published in Victoria Colonist, 1 August 1862). Died in Victoria 12 September 1891."
