Fritz Reiner
One of Gerhardt's favorite productions was the 1964 release "Treasury of Great Music", another 12-LP set for "Reader's Digest". This featured the Royal Philharmonic Orchestra conducted by such eminent figures as Sir John Barbirolli, Sir Malcolm Sargent, Antal Doráti, Jascha Horenstein, Rudolf Kempe, Josef Krips, Charles Münch, Georges Prêtre, and Fritz Reiner.
