yeah, I echo Luvly's statements... although I know who he was 
He lived a long life, filled with doing what he loved and accomplishing his goals and making a positive difference in the world.  I'm sure he had very few regrets and was happy with what he had done.
Although I'm not familiar with all of the technical details, I know that this man made some huge advances in audio, long before computer speakers were even fathomed.  Didn't he basically invent the horn-loaded speaker? 
RIP.  Or, if not in peace, at least boogie-ing away in front of a pair of blaring Klipschorns.
