You can't think of Motown without thinking of Stevie Wonder. Equally, Motown Records clearly couldn't imagine themselves without Wonder, either. They signed him after discovering him as a prodigy, at the age of only eleven. Wonder had as much to do with the distinctive 'Motown sound' as anybody over the course of the 1960s and 70s. He's had too many big hits to name, but we think we can all agree that the world would be musically poorer without 'I Just Called to Say I Love You,' and 'Superstition,' to name but two.
Wonder has been influential far beyond the field of music. In 1980, he was one of the most prominent campaigners to have Martin Luther King Jr's birthday recognized as a national holiday, backing the campaign with the song 'Happy Birthday.' The campaign ended in success. He seems to have retired from music now, although he did perform at the funeral of Aretha Franklin in 2018.
