When Petrus (Pieter) Albertus van Hagen gave a stunning performance in Rotterdam in 1731, he cannot have been more than 17 or so. We do not know how Rotterdam managed to attract this talented musician, but it is possible that the wealthy merchant and former mayor Cornets de Groot played a part in it. It is unlikely that Van Hagen immediately settled in Rotterdam in 1731. We know that he studied the violin with Francesco Geminiani, who was staying in London in 1731; Van Hagen may have travelled through Rotterdam on that occasion. Only in 1741 can he be proved to have been in Rotterdam again, since he and his wife Maria Sophia Salfelt were witnesses at a baptism. In the same year he was appointed organist in the Oosterkerk; later, in 1764, he was to become the organist of the St Laurenskerk. His first wife died in 1750. He remarried in 1753; with his second wife, Catharina Logen from Geilenkirchen, he had three children. By then, Hagen had acquired a new function. At the expense of the aforementioned De Groot, a concert hall with accommodation above it had been opened in Bierstraat, where, from 1756 onwards, Hagen organised Saturday concerts. From the announcements in the Rotterdamse Courant we know many of the programmes. On 16 February 1760, for instance, his six-year-old daughter Elizabeth was the soloist in a violin concerto by Tartini.
