7107 Peiser           Discovered 1980 Aug. 15 by A. Mrkos at Klet.
Named in honor of Benny Josef Peiser (b. 1957), social anthropologist with a particular research interest in neocatastrophism and its implications for human, societal and cultural evolution. A senior lecturer at John Moores University in Liverpool, he launched and now moderates the Cambridge-Conference Network, a scholarly network of some 300 researchers from around the world. Name suggested by J. Ticha, M. Tichy and Z. Moravec, who observed this minor planet at Klet at the 1994 and 1996 oppositions, prior to its numbering.
