Ericsson Dialog

The Ericsson company presented King Carl XVI Gustaf of Sweden with a unique handmade Dialog telephone on his 40th birthday.

In the early 1960s Ericsson hired the Swedish architecture and design company Ahlgren, Olsson & Silow (AOS) to develop Dialog, a new standard telephone that was to apply high end technology and reach international markets.

The handle was made as light as possible to minimize the stress inflicted upon the wrist and blood veins of the speaker during long calls.

The depth and thoroughness of the design is perhaps best depicted by the fact that even the inner lighting of the phone was taken into account: the inside was not left completely dark, to avoid insects inhabiting the product.
