Rolf Harris (born 30 March 1930) is an Australian entertainer whose career has encompassed work as a musician, singer-songwriter, composer, comedian, actor, painter and television personality. He often used unusual instruments in his performances: he played the didgeridoo; is credited with the invention of the wobble board; and is associated with the stylophone. Harris was convicted in 2014 of the sexual assault of four underage girls, which effectively ended his career.
