Larss and Duclos was a photographic studio partnership between Per Edvard Larss and Joseph E. N. Duclos (1863-1917) in Dawson City, Yukon Territory during the Klondike Gold Rush era of the late 19th and early 20th centuries. 
Duclos was born in Quebec and moved to Maine where he learned photography. He moved to Dawson with his wife Emily in 1898 via St. Michael, Alaska and the Yukon River. He mined on Lovett Gulch until he joined the studio. Duclos specialized in portraits while Larss photographed gold rush scenes and scenery.
Larss and Duclos took over the studio of Eric A. Hegg, who arrived in Skagway in October 1897 after a short stop in Dyea. He immediately opened a studio and was joined a year later by his brother and a friend of the two brothers, Peter Andersson, along with Per Edvard Larss in the following spring, who also was a Swedish-American photographer. In 1899, after a year in Yukon, Hegg returned to Skagway and left his studio in Dawson to Larss and Duclos. Duclos was from Quebec.
The pair witnessed the Chilkoot Trail and the Klondike gold rush capturing iconic photographs that are used to illustrate the era.
The partnership dissolved in 1904 when Larss left the area for Denver and Nevada, selling out to his partner. Duclos continued in the studio business until 1914.
