Born Sigmund Esco Jackson in Gary, Indiana in 1951, he was given the name "Jackie" by relatives. Aspiring to be a professional baseball player, Jackie forsook that dream when he became the eldest member of The Jackson Five in 1966. Jackie assisted a co-lead on alongside Michael and Jermaine on four consecutive number-one hits, including "I Want You Back" and "ABC," and took lead in the group's first hit "Enjoy Yourself," as well as "Hum Along and Dance," Wondering Who," "It's Alright," "Wait" and "Torture."

His last performance was with his five younger brothers during Michael's 30th Anniversary Reunion performance at Madison Square Garden in 2001. Jackie currently lives in Las Vegas where he runs Jesco Records, which has signed artists such as rapper Mike Street from the Long Island, New York group Emstate, and his son, rapper DealZ.

Jackie has two children; his son Sigmund Esco II (aka DealZ) and daughter Brandi .
