First name Pieter, born 1721. died 1799.  Got his first job as organist at
age 11.  Studied violin with Tartini; active in Holland and later in
England.In addition to concerti, he wrote sacred and secular vocal music,
as well as instrumental chamber music for strings.  TThat's a rough
summary of the New Grove article on him (which I can access on-line.
There is a recording of his concerti grossi done by the European Community
Baroque Orchestra on Channel Classics.
