At the age of eight, Les Paul began playing the harmonica. After trying to learn the piano, he switched to the guitar. It was during this time that he invented a neck-worn harmonica holder, which allowed him to play both sides of the harmonica hands-free while accompanying himself on the guitar. It is still manufactured using his basic design. By age thirteen, Paul was performing semi-professionally as a country-music singer, guitarist and harmonica player. While playing at the Waukesha area drive-ins and roadhouses, Paul began his first experiment with sound. Wanting to make himself heard by more people at the local venues, he wired a phonograph needle to his guitar and connected it to a radio speaker, using that to amplify his acoustic guitar. As a teen Paul created his first solid body electric guitar using a 2-foot piece of rail from a nearby train line. In the summer of 1945, Paul met country-western singer Iris Colleen Summers. They began working together in 1948, during which time she adopted the stage name Mary Ford. They married in 1949. Their hits included "How High the Moon", "Bye Bye Blues", "Song in Blue", "Don'cha Hear Them Bells", "The World Is Waiting for the Sunrise", and "Vaya con Dios". The songs featured Ford harmonizing with herself, as well as Les Paul's multiple guitars. On August 12, 2009, Paul died of complications from pneumonia at White Plains Hospital in White Plains, New York.
