Frans Tollenaar, borne in 1950, at the edge of Holland, in Den Helder, was busy as a teacher at the secondary modern school.
He passed the exam for drawing and mathematics for it, in the second degree. In his work he always searches for the harmoney mathematics can give.
By looking for the esthetic game in mathematics, one can some of this original art discover again. In the works of Tollenaar they are esthetic aspects of mathematics which form the base of his work.
