Walter Bittner is a fanatical music lover - his religion is the music from T. Albinoni to Frank Zappa - and became a piano technician and piano tuner quasi against his will. For many years he rescued old family heirlooms from the junkyard and made pianos playable again, before he became more and more active in concert service. Just before retirement, Walter Bittner finally rose to the position of university lecturer for the subject "Instrumentology Piano".
