(CNN)Chuck Berry, a music pioneer often called "the Father of Rock 'n' Roll," died Saturday at his home outside St. Louis, his verified Facebook page said. He was 90.
A post on the St. Charles County police Facebook page said officers responded to a medical emergency at the residence around 12:40 p.m. (1:40 p.m. ET) Saturday and found an unresponsive man inside. Resuscitation efforts failed.
"The St. Charles County Police Department sadly confirms the death of Charles Edward Anderson Berry Sr., better known as legendary musician Chuck Berry."
Berry wrote and recorded "Johnny B. Goode" and "Sweet Little Sixteen" -- songs every garage band and fledgling guitarist had to learn if they wanted to enter the rock 'n' roll fellowship.
Berry took all-night hamburger stands, brown-eyed handsome men and V-8 Fords and turned them into the stuff of American poetry. By doing so, he gave rise to followers beyond number, bar-band disciples of the electric guitar, who carried his musical message to the far corners of the Earth.
Some of his most famous followers praised him on social media.
Bruce Springsteen tweeted: "Chuck Berry was rock's greatest practitioner, guitarist, and the greatest pure rock 'n' roll writer who ever lived."
