John Adam Belushi was an American comedian, actor, and musician. He is best known for his "intense energy and raucous attitude" which he displayed as one of the original cast members of the NBC sketch comedy show Saturday Night Live, in his role in the 1978 film Animal House and in his recordings and performances as one of The Blues Brothers. During his career he had a close personal and artistic partnership with fellow SNL actor and writer Dan Aykroyd whom he met while they were both working at Chicago's Second City comedy club. Belushi died on the morning of March 5, 1982 at the age of 33 at the Chateau Marmont in Los Angeles, after being injected with a mixture of cocaine and heroin, known as a "speedball", which led to combined drug intoxication. He was posthumously honored with a star on the Hollywood Walk of Fame, on April 1, 2004.
