The L. M. Ericsson Memorial Room

The telecommunications company Ericsson’s room commemorating its founder, Lars Magnus Ericsson, was moved to Tekniska museet in 1976. It is a unique room made entirely of mahogany, with telephone motifs incorporated throughout the interior. The L. M. Ericsson Memorial Room is available to view for booked groups.

The room was built in 1903 at the telephone manufacturer Ericsson’s premises on Tulegatan in Stockholm, originally serving as a showroom where the company could present its products to customers. In the 1930s, the room was turned into a museum where company employees could study the development of different products. When the company moved to new premises in 1940, the room was restored and became a memorial room dedicated to the founder of the Swedish telephone industry.

The L. M. Ericsson Memorial Room was transferred to Tekniska museet in 1976, where it can now be seen in its original condition by booked groups.

The room’s interior

The unique room consists of two floors and has a floor area of 75 square metres. The magnificent interior — including the walls, staircase, railings and furniture — is made entirely of Honduran mahogany.

The ceiling is richly decorated with original stucco work featuring unique telephone motifs, including little cherubs making phone calls in the corners.

The posts on the balcony railing and staircase are decoratively embellished with telephone details in mahogany. Telephone motifs can also be found in the curtains by the windows.
