Vincent gave painting lessons to Willem van de Wakker (1859–1927). Van de Wakker was a telegraphist in the Nuenen post office and an amateur painter, and after seeing his work at Baijens’ art supply store, Vincent wished to meet him. Van de Wakker lived in Eindhoven, as did Antoon Hermans and Anton Kerssemakers, whom Vincent also taught. He asked them to pay for their lessons in painting supplies. Van de Wakker recalled in 1927:
“Vincent was in no sense an easy teacher; he was sarcastic and not ashamed of cursing fearfully if an error was made, or if his pupil had not brought along enough materials.”
Vincent enjoyed giving painting lessons, as it provided him with company. He therefore considered doing it in Antwerp once he had moved there.
