Mickey Hart (born Michael Steven Hartman, September 11, 1943) is an American percussionist and musicologist. He is best known as one of the two drummers of the rock band Grateful Dead. He was a member of the Grateful Dead from September 1967 until February 1971, and again from October 1974 until their final show in August 1995. He and fellow Dead drummer Bill Kreutzmann earned the nickname "the rhythm devils".
Michael Steven Hartman was born in Flatbush neighborhood of Brooklyn, New York. He was raised in suburban Inwood, New York by his mother, Leah, a drummer, gown maker and bookkeeper. His father, a champion rudimental drummer Lenny Hart, had abandoned his family when the younger Hart was a toddler. Although Hart (who was hyperactive and not academically inclined) became interested in percussion as a grade school student, his interest intensified after seeing his father's picture in a newsreel documenting the 1939 World's Fair. Shortly thereafter, he discovered a practice pad and a pair of snakewood sticks that belonged to his father. "From the age of ten," he recalled, "all I did was drum."
