Known forCommanding RCMP vessel St. Roch; second transit of the Northwest Passage

Henry Larsen was a Norwegian-born Canadian mariner and Royal Canadian Mounted Police officer noted for commanding the RCMP vessel St. Roch on the second navigation of the Northwest Passage and the first west–east transit via Arctic waters. He served as a navigator, shipmaster, and polar pilot whose voyages linked Vancouver, Victoria, British Columbia, Winnipeg, and Arctic communities. His career intersected institutions and events including the Royal Canadian Mounted Police, Imperial Japanese Navy tensions in the Pacific era, and Canadian Arctic sovereignty initiatives.

Early life and education

Born in 1899 in Bergen, Norway, he emigrated to Canada as a young man and settled initially on the west coast in Vancouver. He apprenticed at sea with commercial shipping lines and received practical nautical training aboard cargo vessels calling at Seattle, San Francisco, and Victoria, British Columbia. Larsen supplemented hands-on experience with navigation practice influenced by charts used by the Hudson's Bay Company and techniques common to officers of the British Merchant Navy and officers trained under traditions of the Royal Navy.

Larsen began his maritime career in the era of sail-to-steam transition, serving on merchant ships that traded on the Pacific Ocean and along the North Atlantic Ocean routes. He joined the Royal Canadian Mounted Police marine operations and specialized in Arctic seamanship, winter navigation, and ice piloting. As a master mariner he commanded patrols and supply runs linking Arctic Canada posts such as King William Island, Victoria Island, Cambridge Bay, and Gjoa Haven. His operational duties involved coordination with Canadian defence authorities, civil administrators in Ottawa, and local indigenous communities including Inuit settlements. Larsen's skill as an ice navigator drew comparisons to contemporaries in polar exploration like Roald Amundsen, Fridtjof Nansen, and later comparisons to Richard E. Byrd for polar logistics.

Northwest Passage expeditions

As captain of the RCMP schooner St. Roch, Larsen led multiple expeditions to establish regular seasonal and strategic routes through Arctic waterways. His 1940–1942 eastbound transit followed a path through the Bellot Strait, along the Queen Maud Gulf, and via channels near Melville Island, documenting sea ice conditions and charting practical passages. The voyage built upon earlier transits such as Amundsen's 1903–1906 expedition and provided wartime-era data relevant to allied shipping concerns, informing planners in Ottawa and influencing discussions in the British Commonwealth about northern logistics. Larsen's west–east crossing completed in 1944 made St. Roch the second vessel to traverse the Northwest Passage and the first to make the journey from west to east, a feat publicized alongside Arctic patrol efforts during the Second World War.

His expeditions involved interaction with Arctic communities at ports of call including Holman (Ulukhaktok), Coppermine (Kugluktuk), and Rankin Inlet, exchanging mail, provisions, and navigational information. The voyages contributed to hydrographic knowledge used by the Canadian Hydrographic Service and informed later polar projects executed by agencies such as the Canadian Coast Guard.

Later life and legacy

After active command, he retired to British Columbia, residing in Vancouver and maintaining ties with maritime societies, veterans' groups, and polar researchers affiliated with institutions like the National Research Council (Canada). His written accounts and logbooks influenced polar historians and were cited in retrospectives alongside works addressing Arctic sovereignty debates, Cold War northern defence planning, and Canadian exploration narratives preserved by museums such as the Canadian Museum of History and regional maritime museums in British Columbia and the Northwest Territories. His personal papers and artifacts later informed exhibitions emphasizing the role of RCMP maritime patrols in asserting presence across northern waters.

Honors and commemorations

He received recognition from Canadian institutions and civic bodies for his Arctic service, including honours tied to maritime achievement and public commemorations in Vancouver and Victoria, British Columbia. The vessel he commanded, St. Roch, was preserved and displayed as a museum ship to commemorate Arctic navigation and Canadian northern history, becoming part of public memory alongside other preserved exploration vessels such as HMS Investigator and polar museum exhibits. Geographic features and plaques in Arctic communities were established to mark his voyages and their contribution to mapping the Northwest Passage and reinforcing Canadian presence in the High Arctic.
