Thomas Dreher studied history of art at Ludwig-Maximilians-Universitaet in Munich and wrote a thesis on "Conceptual Art in America and England between 1963 and 1976" (1988, published in German in 1992). Since 1985 he wrote articles and reviews for art journals ("das kunstwerk", "Artefactum", Artscribe", "Wolkenkratzer", "Kunstforum", etc.). His book "Performance Art after 1945. Action Theater and Intermedia Art" was sustained by DFG (Deutsche Forschungsgemeinschaft) and published in German in 2001. Dreher's research on the history of art since 1945 is archived on the website "Intermedia Art" (URL: https: //dreher.netzliteratur.net). "IASLonline Lessons in NetArt" presents his research on net art and net conditions (URL: http: //iasl.uni-muenchen.de/links/lektion0e.htm).
