From: Camera Workers: British Columbia, Alaska & Yukon, 1858-1950
[Trueman] began as a tinsmith in Brampton, but had purchased a photo studio by 1886 and called it the Popular Photograph Parlor. He sold the studio in 1888 and moved to Brandon, Manitoba, to homestead with his wife Minnie (d. 1893). Trueman returned to Ontario and there met and formed a partnership with young Norman Caple from England. The two are supposed to have met in Toronto.
Trueman & Caple travelled the Canadian Pacific Railway line for about a year and then set up headquarters in Vancouver. After the partnership was dissolved, Trueman remained in Vancouver but is not listed in the directories of 1895-1897. He was, however, travelling through the Prairies and appears to have spent most of the time in Medicine Hat between 1894-99. The newspaper references stated he was from Vancouver. He continued to travel extensively and up until two months before his death was managing his Revelstoke branch studio.
He was widowed on January 9, 1893 when his wife died of heart disease at age 31. Trueman was a superb landscape photographer and was one of few West Coast photographers to print his negatives on platinum paper. The first modern public exhibit of his work was produced by the Peter and Catharine Whyte Foundation, Banff, in 1981. Trueman and his wife are buried in Mountain View Cemetery, Vancouver.
