Together with Peter Struycken he initiated the Arnhem school of environmental art.
[2] Hendriks, son of an arborist from Apeldoorn, was initially destined to follow into his father's footsteps.
He attended the horticultural school in Boskoop, but finally opted for a career in the visual arts.
Environmental works of Hendriks can be found in public space in Amersfoort, Gouda and Hengelo.
His paintings are characterized by geometric shapes, in which he uses mathematical sequences, both in content and color.
