People and things Herwig Schopper (right) talks with Jean Teillac, President of CERN Council, at a special Council meeting in April. At this meeting. Professor Schopper was unanimously appointed as the next CERN Director General, to take up office on 1 January 1981. (Photo CERN 208.4.80) Herwig Schopper CERN's next Director General On 25th Apri/f at a specially con vened session of the CERN Council delegates of the twelve CERN Mem ber States unanimously appointed Professor Herwig Schopper as Director General of CERN for the five years 1981-85. He will suc ceed John Adams, Executive Direc tor General, and Leon Van Hove, Research Director General, on 1 January 1981. Herwig Schopper will move to CERN from his present position as Chairman of the Board of Directors at the DESY Laboratory, a position he assumed in 1973. Under his leadership, DESY has enhanced still further its reputation as a leading high energy physics Laboratory — the physics programme on the DORIS electron-positron storage rings has been amongst the most i fruitful in the world, and the rapid construction of the large PETRA search Association which operates On people ring has been one of the major feats the Laboratory. of accelerator building.

Jacques Prentki, leader of CEHN's Theory Division, celebrated his 60th birthday on 17 April. To mark the occasion, some close friends reminisced on different periods in his career: Ph. Meyer spoke on 'good times in Paris', Bernard d'Es- pagnat on 'the pioneering years at CERN', Dan/e/e Amati on 'the Golden age', Tatiana Faberge on 'theory division through the years' and Paul Musset on 'the theorist in interaction'. This was followed by a short concert of chamber music. History of particle physics An International Symposium on the History of Particle Physics was held at Fermilab from 28-31 May. It concentrated on the origins of particle physics back in the 1930s and 40s before the advent of the big particle accelerators. The im pressive list of main speakers in cluded Paul Dirac, Gilberto Bernar- dini, Viki Weisskopf, Carl Anderson, Satio Hayakawa, Robert Serber, Bruno Rossi, Willis Lamb, Julian Schwinger and Murray Gell-Mann. Seen here together with Jacques Prentki (left) at the celebrations at CERN to mark his 60th birthday are Tatiana Faberge of Theory Division Secretariat and Daniele Amati.

(Photo Fermilab) SCIPP at Santa Cruz The Regents of the University of California have approved the forma tion of a new Institute for Particle Physics on its Santa Cruz Campus. Acronymed SCIPP (the Santa Cruz Institute for Particle Physics I it builds on the strength of existing groups of theoretical and experi mental particle physicists. Benefit ting from its close proximity to SLAC, the experimental group (started in 1970) has carried out programmes on inelastic muon- nucleon scattering, early charm searches in pion-nuc/eon scattering and dimuon production, all in colla boration with SLAC Group D. In addition, a tagged photon scattering experiment has been performed at Fermilab. The principal new enter prise of SCIPP is co-responsibility, again with SLAC Group D (plus groups from the Universities of Illi nois and Washington) for the next- generation SPEAR detector, called tevatron proton synchrotron.
