Alexander Borbély became engaged in sleep research almost three decades ago1 . In the early 1970s he built up an animal sleep research laboratory in Zurich and was joined by Irene Tobler in 1975. She published her first paper two years later2 . Human sleep research started in 1980 in collaboration with Dietrich Lehmann and Inge Strauch, and the first human sleep paper appeared in 19813 . Since that time, animal and human studies were pursued in parallel. Peter Achermann joined the lab in 1983 as a computer engineer, and decided in 1985 to switch to research. His first paper appeared two years later4 . Beat Geering started his work in 1990 and devoted his initial efforts to EEG analysis5 . He then became responsible for system development, signal analysis and media projects. Concept and implementation of the present CDROM is to a large extent his work.
