Henry Larsen (explorer)
Henry Asbjørn Larsen (September 30, 1899 – October 29, 1964) was a Canadian Arctic explorer. Larsen was born in Norway, like his hero, Roald Amundsen. Like Amundsen, he became a seaman. Larsen immigrated to Canada, and became a British citizen in 1927 (Canadian citizen in 1947). In 1928, he joined the Royal Canadian Mounted Police (RCMP).
RCMP service 
In 1928 the RCMP commissioned the St. Roch for Arctic service. During its first voyage into the Arctic, Larsen served as mate under a captain that the RCMP hired, but, once in the Arctic, Larsen was appointed captain. Larsen commanded the St. Roch for most of the next two decades, rising to the rank of Sergeant. In the final years of Larsen's career, he was the senior RCMP officer in the Arctic. Following his command of the St. Roch, Larsen was promoted to Inspector with responsibility for all Arctic detachments. For the first twelve years that the ship was in commission, Larsen and his crew took supplies to scattered RCMP posts in Canada's far north. The St. Roch was specially constructed to be able to survive being frozen-in all winter. During the winter, the RCMP officers who formed her crew would use dog sleds to turn the St. Roch into a floating RCMP outpost. During this time, the St. Roch was the only Canadian presence in the far north, carrying out various governmental duties.
Exploring the Northwest Passage 
1940-2 west-east: This journey was the second ship crossing of the Northwest Passage and the first from west to east. The route was nearly the same as Roald Amundsen's 1903 coast-hugging east-west crossing except that Larsen used the Bellot Strait. Documents found in the RCMP archives in the 1990s show that the voyage was somehow connected to a Canadian plan to occupy Greenland after the German invasion of Denmark. The Germans could have occupied the island, seized the cryolite mine and used the island as a U-boat base. The Canadian plan was blocked by the United States but Larsen's voyage went ahead anyway. The St. Roche left Vancouver in June 1940. After trouble with ice east of Point Barrow he decided to winter at Walker Bay (Northwest Territories) on the west coast of Victoria Island at the entrance to Prince of Wales Strait. In July 1941 the ship was released from the ice and Larsen followed the coast east and reached Amundsen's Gjoa Haven by the end of August. Turning north up the channel of he was struck by the full force of the ice just north of King William Island. In early September he found refuge at a place called Paisley Bay on the west coast of the Boothia Peninsula near the original North Magnetic Pole. In August 1942 he forced his way out of the ice, went north and with difficulty passed the Bellot Strait. At the other end he found civilization of a sort at the Hudson's Bay Company post at Fort Ross, Nunavut. He then continued through Prince Regent Inlet, Lancaster Sound and Davis Strait, reaching Halifax on 11 October 1942.
1944 east-west: This was the third ship crossing of the Northwest Passage, the second east-west crossing and the first to be made in one season (7295 miles in 86 days). Instead of the standard route along the coast he used the Parry Channel and Prince of Wales Strait. Fitted with a more powerful engine, the St. Roch left Halifax on 25 July 1944 and by 20 August was at Beechey Island. Continuing west he reached William Edward Parry's Winter Harbour on Melville Island. As usual for explorers at this place, he tried to enter McClure Strait to the northwest and, as usual, was blocked by ice. Next he turned southwest and passed through the Prince of Wales Strait, apparently the first ship to do so. Passing Walker Bay where he had wintered four years previously on 4 September he reached the Hudson's Bay Company post at Holman Island. Just one day before this post had been supplied by the Fort Ross which had sailed from Halifax and through the Panama Canal and Bering Strait. With about a month left before the ice would probably close in, he hurried west, passed through the Bering Strait and reached Vancouver on 16 October.
In 2000, as a millennium project, the RCMP renamed one of its vessels the St. Roch II, and sent it to recreate Larsen's first voyage.
Larsen's explorations and Canadian sovereignty 
Some believe the real purpose of the voyages of discovery was not to patrol the Arctic searching for evidence of German infiltrators, but rather to protect Canadian interests from her American allies. There were difficulties in the American/Canadian alliance during World War II, manifested during the construction of the Alaska Highway.
Larsen Sound — a body of water located in the Arctic to the west of Boothia Peninsula and north of Victoria Strait — was named for him. In 1959, the Royal Canadian Geographical Society awarded him the first Massey Medal.
