UCSD graduate students under the direction of Herbert Marcuse started a number of journals, including the philosophy journal Alternatives, which I discussed in an earlier post. Lowell Bergman, Angela Davis and others started the Street Journal and San Diego Free Press (see the Library of Congress entry here; we are researching those journals and will post more later).
For these efforts they, predictably, suffered repression at the hands of San Diego police and probably federal agencies including the FBI and CIA as well (at least according to this 2006 U.S. News and World Report article). They were aided and supported by heroic San Diego Superior Court judge Roger Ruffin, about whom I also wrote about in a recent post.
It seems that they headquartered at the historic Franz Merzman House, at Second Avenue and Thorn Street, near downtown and Balboa Park, according to this San Diego Union Tribune piece. One can see a picture of the house here on google maps. I am interested in this detail because I happen to live on Thorn Street myself, though on the other side of the park.
