George Jan Hendrik (Geo) Poggenbeek (1853–1903) was a 19th-century painter from Amsterdam, the Netherlands who maintained close contact with the Hague School.
Poggenbeek began painting at the age of nineteen, first studying under J. D. Veldhuizen and later working at the Amsterdam Rijksakademie van beeldende kunsten.
For a while he painted ducks and calves under willows exactly like Willem Maris, but he more lastingly influenced by Anton Mauve, whose soft, light tone and delicate quiet lyricism he shared.
Each influenced the other but Poggenbeek, the more progressive, generally gave the sky a smaller place in his compositions, in which elements are related in a broadly geometric arrangement.
[1] According to the RKD he gave advice to the painter Hendrik Bloem, and taught Marie van Regteren Altena and Johan Frederik Cornelis Scherrewitz.
