Bell tribute

In 1922, every telephone in North America was silent for one minute at sunset marking the time funeral services were taking place for Alexander Graham Bell. He was laid to rest in a tomb blasted in the solid rock at the peak of Beinn Bhreagh Mountain on his estate in Nova Scotia, Canada. A watch tower had been built there years earlier by the inventor. His coffin was made in the inventor's own workshop by his laboratory staff.

Bell had died two days earlier on 2 Aug 1922..«[Image: The burial of Alexander Graham Bell on his estate.]
