Mark Sweeten Wade (November 23, 1858 – 1929)[1] was a medical doctor and historian of early British Columbia history. A medical doctor at the Kamloops Home for Men in the 1920s, he was able to interview many veterans of the province's early gold rush, including many of the more famous names in the history of the Cariboo Road, the Cariboo Gold Rush and the Overlanders of 1862 led by Thomas McMicking.[2][3] He also wrote on medical legislation and hospital policy in the province of British Columbia as well as a biography of explorer Alexander Mackenzie. His works have served as an important source of biographical and historical detail by later historians.
