Nienhuis 90 - Cylinder Blocks - English

The Original Montessori Craft.

We go back to 18 October 1922, when Maria Montessori and Albert Nienhuis discussed several materials with a great eye for detail. After more than 90 years we love to share some of their considerations.

Albert Nienhuis “Are the cylinder blocks we presented to you precise enough?” Maria Montessori “The Dutch Cylinder Blocks which have been presented to me, are very adequate, especially because the cylinders slide down very slowly into the holes.”
