Lewis Telle Cannon (April 22, 1872 – October 10, 1946) was an early 20th-century architect in Salt Lake City, Utah who designed several buildings throughout the intermountain west. Cannon was trained at the Massachusetts Institute of Technology and after returning to Utah began a firm with Ramm Hansen for a brief time in 1908 and then another firm with John Fetzer (architect) named Cannon & Fetzer in 1909. Cannon & Fetzer existed until 1937 and produced civic buildings, meetinghouses, and residences, many of which remain and are listed on the National Register of Historic Places.[1]
Lewis was born to the Church of Jesus Christ of Latter-day Saints leader George Q. Cannon and Martha Telle Cannon in Salt Lake City on April 22, 1872.[2] Cannon was also a member of this Church. He was the half-brother to architect Georgius Y. Cannon. Lewis died October 10, 1946, in Salt Lake City, and was buried at Salt Lake City Cemetery.[3]
