aap van den Ende was born in Delft in 1944. The painter studied at the Koninklijke Academie van Beeldende Kunst in The Hague. At the beginning of his career, he mainly painted in a geometric abstract style, in which systematics often played an important role. Van den Ende based these works on the idea that reality is formed by laws. He depicted these laws in alternating colors within a recurring pattern. From 1970 he painted in a looser style in which figurative forms can also be recognized. Van den Ende is still active as an artist and his works are shown in exhibitions of renowned museums.
