Re: Lincoln Brigade and Spanish Civil War #usa
Jack Shiffman and many others in the International Brigade are listed and discussed in a number of reports of the Congressional Hearings of Un-American Activities (1938), Investigation of un-American Propaganda Activities (1944), and Scope of Soviet Activity in the U.S. : Hearings before the United States Senate Committee on the Judiciary, Subcommittee To Investigate the Administration of the Internal Security Act and Other Internal Security Laws (1956-1959). These are long reports, but if anyone is interested I'll be happy to make the full pdf documents available online through my GoogleDrive for a few months. Contact me directly by e-mail.
Lots of excellent resources on the International Brigades have already been provided by other respondents above--thanks! A few others include the International Institute of Social History in Amsterdam https://search.iisg.amsterdam/ which holds a lot of photographs of the Int'l Brigades and related material; Polish, Austrian, and Hungarian participants in the International Brigades can be found in the Vera and Donald Blinken Open Society Archives at Central European University in Budapest https://catalog.osaarchivum.org/ , and Martin Sugarman's "Against Fascism – Jews who served in The International Brigade in The Spanish Civil War" https://www.marxists.org/subject/jewish/spanjews.pdf (Sugarman is Archivist of the Association of Jewish Ex-Servicemen and Women, Jewish Military Museum).
