Stevland Hardaway Morris (born May 13, 1950), known professionally as Stevie Wonder, is an American singer, songwriter, musician and record producer. Wonder is credited as a pioneer and influence by musicians across a range of genres that includes rhythm and blues, pop, soul, gospel, funk, and jazz. A virtual one-man band, his use of synthesizers and other electronic musical instruments during the 1970s reshaped the conventions of R&B. He also helped drive the genre into the album era, crafting his LPs as cohesive, consistent socially conscious statements with complex compositions. Blind since shortly after his birth, Wonder was a child prodigy who signed with Motown's Tamla label at the age of 11, where he was given the professional name Little Stevie Wonder. In 1963, the single "Fingertips" was a number-one hit on the Billboard Hot 100 when Wonder was 13, making him the youngest artist ever to top the chart. Wonder's critical success was at its peak in the 1970s. His "classic period" began in 1972 with the releases of Music of My Mind and Talking Book, the latter featuring "Superstition", which is one of the most distinctive and famous examples of the sound of the Hohner Clavinet keyboard. His works Innervisions (1973), Fulfillingness' First Finale (1974) and Songs in the Key of Life (1976) all won the Grammy Award for Album of the Year, making him the tied-record holder for the most Album of the Year wins, with three. He is also the only artist to have won the award with three consecutive album releases.
