Today is the centennial of gospel legend Mahalia Jackson's birth. She was born in Uptown New Orleans and became a prominent singer in her church by the time she was a teenager. She released the million-selling single "Move on Up a Little Higher" in 1948 and in her career collected five Grammys. Jackson brought new audiences to gospel music, became involved in the Civil Rights movement and refused to sing the blues. She died in 1972.
