The Waikiki Natatorium War Memorial is a war memorial in Honolulu, Hawaii, USA, built in the form of an ocean water public swimming pool. The natatorium was built as living memorial dedicated to "the men and women who served during the great war" (now known as World War I). Creation of the memorial In March 1918, the Daughters and Sons of Hawaiian Warriors first proposed a memorial to the more than 10,000 men from the then Territory of Hawaii who volunteered to serve in the great war. The Honolulu Ad Club agreed with the idea and on November 20, 1918, appointed an investigative committee led by Colonel Howard Hathaway, Ned Loomis, and W.D. Westervelt to bring together representatives from all civic organizations to collaborate on the concept of a memorial beginning with a conference which was held on December 6, 1918. At this meeting Colonel Hathway was appointed Chairman and Fred W. Beckley was appointed Secretary of the general committee on a war memorial. At the second meeting, a subcommittee was formed to investigate and prepare a report on a design and cost estimates of a war memorial. This subcommittee included: Princess Kalanianaole Mrs. Walter Macfarlane Mrs. A. A. Young Mrs. J.M. Dowsett C.R. Hemenway Senator John H. Wise J.D. McInerny Upon the report of the subcommittee, a plan to acquire the former William G. Irwin Estate (located between the shoreline and Kapiolani Park in Waikiki) for a public park for the memorial gained unanimous support. To pursue the idea, John Guild, Mrs. Walter Macfarlane, Mrs. John Baird, Mrs. A.G.M. Robertson and Alexander Rume Ford took the lead in pursuing the property. A bill passed through the territorial legislature with "practical unanimity" according to the Historical Commission of Honolulu. The act was signed by the governor on April 29, 1919 providing for the acquisition of the Irwin property through the sale of territorial bonds and provided that the property should be named "Memorial Park" for the memorial concept being discussed by the committee on a war memorial. Memorial Park was formally dedicated on the one year anniversary of the signing of the armistice with the dedication organized by the recently formed organization, the American Legion. In 1920, with the memorial's site now acquired, a committee to study and recommend designs for the memorial itself was organized.
