Lewis Niles Black (born August 30, 1948) is an American stand-up comedian, author, playwright, social critic and actor. He is best known for his angry demeanour and belligerent comedic style, in which he often simulates having a mental breakdown. His comedy routines often escalate into angry rants about history, politics, religion, or any other cultural trends. He hosted the Comedy Central series Lewis Black's Root of All Evil and makes regular appearances on The Daily Show with Trevor Noah delivering his "Back in Black" commentary segment, which he has been doing since The Daily Show was hosted by Craig Kilborn.
When not on the road performing, Black resides in Manhattan, but also maintains a residence in Chapel Hill, North Carolina. He is also a spokesman for the Aruba Tourism Authority, appearing in television ads that first aired in late 2009 and 2010, as well as the voice of Anger in 2015's Pixar film, Inside Out. He was voted 51st of the 100 greatest stand-up comedians of all time by Comedy Central in 2004; he was voted 5th in Comedy Central's Stand Up Showdown in 2008 and 11th in 2010. Black has served as an "ambassador for voting rights" for the American Civil Liberties Union, since 2013.
