Career
Pieterszen was among the six founders and governors of the Evangelical College (Vlaamsche Opleidingsschool) in Laeken, near Brussels, established in 1875 under the direction by North. de Jonge. 16–17 July 1878, Ds. Van Gogh"s request of 26 December 1878, to join the work of the committee, was evidently supported Pieterszen, and so Vincent got a temporary contract for six month on approval. Even when the committee headed by Pierre Péron (1828–1920), minister of Dour (1869–1882) and the part of the Borinage district Van Gogh was appointed to, in 1879 refused to extend his contract, Van Gogh still found Pieterszen"s door open to discuss his wish to work somewhere between art and religion.
Soon, however, Pieterszen fell ill and died within short, in April 1880, little after Van Gogh"s escape back to the Borinage.
