Founded by Alexander Graham Bell along with Gardiner Greene Hubbard and Thomas Sanders (the fathers of two of Bell’s deaf students), the company is located initially at 125 Milk Street and moves to Bowdoin Street in 1930. It opens a Boston-Chicago long distance line on February 7, 1893 and a Boston-San Francisco line on September 27, 1915. The company is subsumed by the American Telephone & Telegraph Company, incorporated in New York on December 31, 1899. It becomes Nynex in 1984, merges with Bell Atlantic in 1997, and later merges with GTE to create Verizon.
