Stevie Wonder
Person
Stevie Wonder, blind since infancy, was named a United Nations Messenger of Peace in 2009 with a focus on disability, and lobbied for the Marrakesh Treaty of 2013, which makes it easier to produce and share books in braille and other accessible formats across borders. At the 2016 Grammys he read the winner from a braille card and called for everything to be accessible to everyone. His advocacy is specific, persistent and tied to real legislation.
