One of the core themes of the Cypress I-880 Replacement Project is the confrontation between labor and capital in the railroad yards of West Oakland. There, between 1920 and 1930, an African-American named Morris "Dad" Moore, born in slavery, became the first known figure west of the Rockies to organize his fellow workers in their historic fight against the powerful Pullman Corporation. Under the influence of A. Philip Randolph, and inspired by the socialism of the Harlem Renaissance a continent away, Dad Morre joined the International Brotherhood of Sleeping Car Porters and became the Organizer of its Western Division. Fired from the Southern Pacific railroad yards, Moore set up his own offices, organized in person, and maintained a strategic correspondence with his friend Milton Webster at the Brotherhood's headquarters in Chicago. This paper, based on vital records and on primary document sources, presents new data on Moore's life history and summarizes his efforts and his influence on national affairs. In light of these investigations it is clear than Moore, a patriarch of the African-American labor movement, personifies much that is central to the interpretation of historical archaeology in West Oakland.
