Adrianus Hendrikus "Arie" “Jacques” Witjens (11 April 1881 – 7 December 1956) was a Dutch painter known for his landscapes, cityscapes and figures of his native Netherlands and Argentina, where he lived after 1920.
Witjens was commonly addressed as "Arie" in the Netherlands and later added “Jacques” to his name to project a more artistic image.
He became a successful painter and exhibited regularly in prestigious salons of Argentina: In 1947 Witjens won the award for the best landscape of the Delta in the Salón de San Fernando, Buenos Aires.
His style remained true to his roots, giving his delicate views of Buenos Aires, Tigre, Tandil, Balcarce and Córdoba a calm and airy feel.
He befriended and exhibited with other artists, such as British Stephen Robert Koekkoek, and Argentinians José Félix Rolla, Fernando Fader, Miguel Burgoa Videla, Alberto M. Rossi, and Luis Aquino.
