Amos Dolbear

Amos Emerson Dolbear (November 10, 1837–February 23, 1910) was an American inventor. His patents interfered with Guglielmo Marconi's planned activities in the US.

He invented the first telephone receiver with a permanent magnet in 1865, 11 years before Alexander Graham Bell patented his model. Later, Dolber couldn't prove his claim, so Bell kept the patent.

Dolbear was a graduate of Ohio Wesleyan University, in Delaware, Ohio.
