You might or might know the name Mike Post, but if you're around my age (or older), you've definitely heard his work.
Mike Post, along with frequent collaborator Pete Carpenter, was responsible for some of the best and iconic TV theme songs in the '70s and '80s, as well as some later ones. Here's a partial list:
The Rockford Files
The A-Team
Hill Street Blues
The Greatest American Hero
Law and Order
Doogie Howser, MD
Blossom
LA Law
Hunter
Quantum Leap
Magnum PI
NYPD Blue
There was no better theme song writer in the history of TV.
The only really memorable theme song from that era not involving Post was Hawaii Five-O, which was written by Morton Stevens in 1968, a bit before Post's time.

The themes from Rockford and Greatest American Hero both became Top 40 radio hits at the time.
Post was 30 years younger than Carpenter, so he presumably did most of the work when the two collaborated. Carpenter passed away in 1987 at the age of 73. Post is still alive and will be turning 81 next month.
