Lodge History | Eureka Lodge #20 of F&AM --> Eureka Lodge #20 of F&AM Seattle's Masonic Lodge for Science and Engineering Lodge History Freemasonry in Washington began with Olympia #1 Lodge in 1852. Freemasonry in Seattle began with St Johns Lodge #9, chartered in 1860. Eureka #20 Lodge was chartered on September 4, 1873. Eureka met in several locations before the Main Masonic Temple was completed in 1916 at Harvard and East Pine streets in Seattle, which became the home for Eureka for the next 53 years. Eureka then moved to the Green Lake Masonic Temple in 1969. In 1992, Eureka received funds for its stock in the Main Masonic Temple when the building was sold. Those funds combined with the assets built up over the years and prudent investment now provides the lodge with sufficient income for operating expenses and a reasonable level of Masonic charity. Declining membership in recent years has led to consolidation of some local lodges. Seattle Lodge No. 164 merged with Eureka in 1980. The lodge has filled an active place in the life of the community and the membership has included many who have by their actions helped formulate the ideals and set the standards promoted by the Craft. Members have included an early City Treasurer, a State Treasurer, Grand Masters of Oregon and Washington, a Judge of the Supreme Court, a State Adjutant General and a long time King County Treasurer, Melvin J. R. Williams who was Master in 1937 and Secretary of the lodge for twenty-two yea
