Edwin Ellsworth Peabody (February 19, 1902 – November 7, 1970) was an American banjo player, instrument developer, and musical entertainer whose career spanned five decades.

During this period he received the nicknames "Happiness Boy" (for his ebullient personality, especially when performing) and "Little Eddie" (a comic reference to his short stature).

His energetic playing style, which included fast triplets, glissandos and cross-picking simulating the sound of two banjoists, prompted a 1920s reviewer to nickname him "King Of The Banjo"—a sobriquet he retained the rest of his life.

Commander, performed in shows for servicemen, and directed the music and band departments of the Great Lakes Training Station near Chicago, Illinois.

In 1948, the Art Mooney Orchestra resurrected the 1920s standard I'm Looking Over a Four Leaf Clover and created interest in both nostalgic music and the banjo.

[citation needed] According to one broadcast veteran,[4] a radio announcer once mis-introduced Peabody by saying, "Ladies and gentlemen, Mr. Eddie Playbody will now pee for you".

Peabody continued to perform until his death in 1970, at age 68, due to a brain hemorrhage suffered while onstage at the Lookout House Supper Club in Covington, Kentucky.
