Bill Palmer Wikipedia
Bill Palmer (1917–1996) invented a 'quint' system which was later patented by Titano as used in their line of converter (or "quint") bass accordions.
He made many written contributions to magazines for the promotion of the Piano Accordion, including Accordion World. Some of the more important articles about his beliefs for improving the instrument and current style of playing have been gathered at The Classical Free-Reed, Inc web site.
