Those of us who knew Phyllis Jacobson and her husband Julie will realize that her death brings to a close a long and rich chapter in the history of the revolutionary and democratic socialist left in the US. She was the last of a small but heroic generation. Starting with the YPSL Fourth International, the youth section of the Socialist Party that split under Trotskyist leadership to set up the Socialist Workers Party in 1938 she and Julie ended up in the Workers Party (later the Independent Socialist League) when it was formed in 1940.
