Today is National Disc Jockey Day,

celebrated in remembrance of the death of Albert James “Alan” Freed, (AKA Moondog,) the man who coined the term “Rock ‘n’ Roll”.
The first DJ, or Disc Jockey, was sixteen-year-old student Ray Newby,
who played the first records over the airwaves at Herrold College of Engineering and Wireless located in San Fernando, California, in 1909.
