Moses Gerrish Farmer
Born February 9 1820 – Died May 25 1893
Improvement in Electromagnetic Alarm-Bells
Patent No. 8,920
Inventor and manufacturer Moses Farmer pioneered the practical application of electricity, using it to drive numerous inventions, including the first electric fire alarm system and the “self-exciting” dynamo.
Born in Boscawen, New Hampshire, Farmer attended Dartmouth College. After graduating in 1840, he began working on an electric striking apparatus for a fire alarm service with William Channing. The system had a signaling mechanism that triggered a special water motor that drove the electric dynamo. Their alarm system was an immediate success following the system’s installation in Boston in 1851, the first electric fire-alarm system in the United States.
