Known at various points as Michael Callan, Mickey Calin, and Martin Calinieff, Mr. Calin was born in Philadelphia November 22, 1935. A lifelong go-getter, he learned to dance from the artists who would pass through his father's luncheonette, trading free milkshakes in exchange for dance steps. He favored ballet and tap, and later acrobatics, as an outlet for the kinetic energy that simmered underneath his skin, waiting to explode at a moments notice.
