In June 1923, President Warren G. Harding embarked on an ambitious journey across the United States. Called the “Voyage of Understanding,” the historic trip included the first visit of a sitting president to the U.S. territory of Alaska as well as the first international visit of an American president to Canada. The voyage also marked the final weeks of Harding’s life. Before he could complete his return to Washington, the president died suddenly from a heart attack. Stereographic photography fr
