The boilermakers in San Francisco have a long history of organization. By 1867, a group
identified as the Journeymen Boilermakers' Protective Union became a part of the San
Francisco Trades' Union. They were among the founding unions of the Federated Iron Trade
Council of San Francisco in 1885
. The International Brotherhood of Boilermakers, Iron Ship
Builders and Helpers was organized in 1893, and the San Francisco lodge received its
charter in 1900.
