Alexander Graham Bell (March 3, 1847 – August 2, 1922) was an eminent Scottish-born scientist, inventor, engineer and innovator who is credited with inventing the first practical telephone.<br/><br/> Bell's father, grandfather, and brother had all been associated with work on elocution and speech, and both his mother and wife were deaf, profoundly influencing Bell's life's work. His research on hearing and speech further led him to experiment with hearing devices which eventually culminated in Bell being awarded the first U.S. patent for the telephone in 1876. Bell considered his most famous invention an intrusion on his real work as a scientist and refused to have a telephone in his study.<br/><br/> Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications, hydrofoils and aeronautics. In 1888, Bell became one of the founding members of the National Geographic Society.
The wheels of the 'pedespeed' measured 14 to 15 inches in diameter and were attached to a stirrup and foot bed by an appendage made of hickory. The appendages had metal plates fastened to them with short axles protruding from their centers which allowed the wheels to turn.<br/><br/> The stirrups were made of wooden strips about 3 inches wide and were bent to form a loop, at the bottom of which sat the foot bed. The foot bed had a toe strap and heel clasp to hold the rider’s foot in place. A second wooden strap was fitted to the top of the stirrup and was fastened around the rider’s calf.
