Dom Hans van der Laan (1904 – 1991) was a Dutch Benedictine monk and architect. He was a leading figure in the Bossche School. His theories on numerical ratios in architecture, in particular regarding the plastic number, were very influential. Van der Laan was not interested in the dimensions of the spaces themselves, but in what the proportions of dimensions brought about in humans. Design studio Autobahn, together with spatial designer Willem Noyons, developed a digital version of the Alphabet in Stone by Van der Laan, also based on these proportions.
