BACK TO INDEX FOCUS ON CAE | Celebrating the past to look into the future: the Franco Bertolani museum

CAE was born in 1977 from the will of four electronic telecommunications engineers and researchers of the Marconi Foundation, with a very specific pur- pose: providing public and private bodies with the most advanced technologies for monitoring the environmental risk caused by natural phenomena. On the occasion of the 40th anniversary of CAE, we created a company museum named after one of its four founding partners: Engineer Franco Bertolani, who passed away in August 2016 and always wanted to dedicate a space to the exhibi- tion of items that have made the history of CAE. Actually, today CAE is the leading Italian company in many services such as design, construction and maintenance of systems and technologies for multi-hazard monitoring and alert.
