Logitech is 40 years old!

Founded on October 2, 1981 to develop word processing software, Logitech immediately became interested in the mouse developed at EPFL and began producing mice a year later.

The Musée Bolo has a copy of Doug Engelbart’s original mouse (1968) and preserves prototypes of EPFL mice from 1972 to 1978 and the famous Guignard mouse (1980), subcontracted to Dépraz SA and redeveloped by Logitech.

Musée Bolo owns one of the most extensive collection of machines and objects related to information technology and its brief history.

Musée Bolo is managed by the foundation Mémoires Informatiques, a recognized public-interest organization. An association of friends contribute dynamically and efficiently to the maintenance and preservation of the museum’s machines. All are volunteers. Member of the Swiss Museums Association (AMS), Musée Bolo rose to be one of the most important computer museums in Europe. Hosted by the Ecole polytechnique fédérale de Lausanne (EPFL), its presence extends itself today well across the swiss borders, not only to computer lovers, but also to a greater and younger audience faced daily with computing technology and its avatars.

Due to the global pandemic, the museum temporarily closed.

However, every first Saturday of the month, we organize guided tours for families or individuals. Registration required. 25 people maximum.
