In 1990, Willem moved to
Iceland. At first he lived in
Stykkishólmur, then in
Siglufjörður,
Selfoss,
Stokkseyri and finally in
Neskaupstaður. Willem left Iceland in 1994. Two municipalities in Iceland bought paintings from Willem, the towns of Siglufjörður and Neskaupstaður. The media in Iceland interviewed him on several occasions and he was noted for his unique style of painting. He lived in Germany and Ireland for a number of years, and then went back to the Netherlands. He had been suffering from cancer for the last two years of his life, and died at
Dokkum in
Friesland. Willem's art developed over the years but he adhered to
abstract expressionism, taking in the impressions of the environment and then putting them down on paper and canvas as they affected him by memory. Mountains, valleys, rock formations and the sky often supplied him with motives of this kind. As a rule he did not travel with his painting gear but went walking on long treks, gathering impressions. Then, after he returned home, he created his artwork. Willem held numerous art exhibitions during his life in the Netherlands, France, Iceland, Germany, Morocco and Ireland. His painting style was mostly abstract expressionism, although he experimented with several other styles. He used oil on canvas and watercolors on paper for his work. During his later years Willem used compositions of sea shells, flowers, stones and other natural objects as motives for digital photography. He had been using photography to assist in the artistic process since he lived in Maastricht. ==Personal life==
