An artist of the Dutch school, Pieters typically painted genre scenes, portraits, nudes, interiors, landscapes, and seascapes. In his reference book Dictionary of Belgian Painters born between 1750 & 1875, art historian Berko writes: [Pieters’] paintings, tinged with slightly melancholic realism, are full of calm and serene feeling.” In addition to being a very skilled artist in oils, he was also an accomplished draftsman and engraver. First a student at the Academy of Amsterdam, he went on to study under the highly acclaimed painters Thomas Verstraete and C. Verlat at the Antwerp Academy of Fine Art. He lived in Antwerp until 1886, and then traveled to Blaricum, and eventually to Paris in 1896. During World War I, he voyaged to London and Scotland, eventually settling in Laren in 1917.
Pieters exhibited in many cities throughout Europe, including Paris at the Salon des Artistes Francais, and in Scotland at the Royal Scottish Academy in 1913. From 1895 to 1905, he showed a number of canvases in Amsterdam. In 1896 he was awarded a third place medal, followed by a silver medal in 1900, both at the Exposition Universelle. He was made a member of the Pulchri Studio at The Hague, the Academy of Antwerp and of Arti et Amicitiae in Amsterdam.
