Dennis Carl Wilson (December 4, 1944 – December 28, 1983) was an American drummer, singer and songwriter. He is best known as a founding member of the rock band The Beach Boys, alongside his brothers, Brian and Carl, and cousin, Mike Love. Wilson was a member of the band from its formation until his death in 1983, recording twenty-four studio albums. In 1977, he released a solo album, Pacific Ocean Blue, to widespread critical acclaim.
Born in Inglewood, California, Dennis was the middle brother of fellow Beach Boys members Brian Wilson and Carl Wilson. Dennis Wilson was also the only regular surfer of the group, and his personal life exemplified the beach lifestyle that the group's early songs often celebrated. His prominence in the group as a writer and lead vocalist increased as their careers went on into the late 1960s and 1970s.
