Historical perspective of the society

The society was founded in 1982. The aim of the society is to promote basic and clinical research as well as clinical activity concerning sleep and wakefulness. It started with a very small group of people working in sleep research and the first president was Prof. Georges Franck. During the years the society has grown, not only in members but also in the fi eld of interest. Both sleep research and sleep medicine has widened and today we are proud of recognizing many different professions coming together sharing their common interest of sleep.
