's-Hertogenbosch 1841 -- 1912 ' s-Hertogenbosch.
In the course of the 19th. century the versatile painter Petrus Marinus Slager specialized in the portrait-genre, of which he was an important representative. His portrait of the ' Veterans of Waterloo' is a skilful group-portrait but also an historic document.
For forty years Petrus Marinus was connected to the "Royal School" in 's-Hertogenbosch (predecessor to the present-day Academy of Arts). Antoon Derkinderen, Pieter Josselin de Jong, Jan Sluyters, Herman Moerkerk and Jan and Theo van Delft were among his pupils. Moreover, he gave lessons to his children Piet, Frans, Jeannette and Corry.
