Brantford, city (1991 pop. 81,997), S Ont., Canada, on the Grand River. It is a leading manufacturing city, noted particularly for its large farm implement factories. The city was named for the Mohawk chieftain Joseph Brant, who led the Six Nations of the Iroquois to the region after the American Revolution and who is buried in the old Mohawk Church near the city. The Mohawk Institute, a Native American residential school, is nearby. Alexander Graham Bell was living in Brantford in 1876 when he made his first successful experiment in the transmission of sound by electric wire. A museum, formerly his home, exhibits the first telephone.
