The Guam Historical Club was a small group of people interested in Guam history in the 1950s and 1960s. Led by Paul Souder and Agueda Iglesias Johnston, the Club helped tell the story of Guam history at the Guam Museum when it was located at the Garden House at the Plaza de España. Members helped care for the artifacts, engaged with visitors as needed, and worked in cooperation with the Guam Women’s Club who staffed the museum at the time.
