Stevland Hardaway Morris (né Judkins; born May 13, 1950), known by his stage name Stevie Wonder, is an American singer, songwriter, record producer, and multi-instrumentalist. A child prodigy, he is considered to be one of the most critically and commercially successful musical performers of the late 20th century. Wonder signed with Motown's Tamla label at the age of 11, and he continued performing and recording for Motown into the 2010s. He has been blind since shortly after birth. Among Wonder's works are singles such as "Signed, Sealed, Delivered I'm Yours", "Superstition", "Sir Duke", "You Are the Sunshine of My Life" and "I Just Called to Say I Love You"; and albums such as Talking Book, Innervisions and Songs in the Key of Life.
