Marcus Frederick Jensen, former Alaska legislator, big game guide and businessman, was born on August 8, 1908, in Westhope, North Dakota. In 1929, after four years of university and civil engineering training, he came north to Juneau, Alaska. He married Mamie Johana Feusi of Douglas on December 5, 1933, and since then has made Alaska home. They have one son, John Marcus Jensen, born on May 1, 1935.

Marcus Jensen was involved in the development of Douglas as businessman, president of Douglas Cannery (salmon), mayor (1945-1947) and two-term city council member. Although his family had long been staunch Republicans, he became disillusioned with the party in the late 1940s. When urged to run for the Juneau seat in the Territorial House of Representatives, he filed as a Democrat. He was elected and soon became heatedly involved in exposing and investigating what he saw as violations against the public interest.

Mr. Jensen's political career eventually grew into 11 years in the Alaska Territorial and State Legislatures (House of Representatives, 1949-1951 and 1961-1963; Senate, 1953-1957). He unsuccessfully ran for Secretary of State on the Republican ticket in 1966. After 25 years as a professional hunting guide near Chichagof and in southcentral Alaska, he was appointed chairman of the Guide Licensing & Control Board in 1973, and has maintained an active interest in hunting and subsistence issues to the present time.

Mamie Jensen has been active in various community projects and maintained a historic photograph collection.
