Born in Los Angeles, California and raised Catholic, Hickman is the younger brother of child actor Darryl Hickman. An early screen appearance was in the 1942 Our Gang comedy Melodies Old and New. Dwayne and Darryl co-starred in an early episode of the syndicated military drama Men of Annapolis, filmed at the United States Naval Academy in Annapolis, Maryland.
As a teen, he and Darryl guest-starred in a 1950 episode of The Lone Ranger entitled Two Gold Lockets, and in 1955 he appeared in another episode entitled "Sunstroke Mesa".
He gained wide notice as "Chuck" on The Bob Cummings Show from 1955-1959. At the time, he was studying at Loyola.
Hickman was one of the first stars to have a breakout character in the series. Hickman considered Cummings a childhood television hero and has said that Cummings taught him everything he knows about acting.
He worked with and was friends with Cummings throughout five seasons.
While still on the Bob Cummings Show in 1958, Hickman was cast in the lead of The Many Loves of Dobie Gillis, which aired on Columbia Broadcasting System from 1959-1963. Although at the show"s debut the Dobie character was a teenager in high school, Hickman was then twenty-five years old. After playing Dobie for four years (with fellow former Loyola student Bob Denver as his sidekick, Maynard G Krebs), Hickman found himself stereotyped as a "youngster" when he was too old for such roles.
