Aulis Blomstedt

Yrjö Aulis Uramo Blomstedt (28 February 1906 – 21 December 1979) was a Finnish architect and professor of architecture at the Helsinki University of Technology.

Blomstedt spent his childhood in the city of Jyväskylä, and attended the same school as the renowned architect Alvar Aalto.

To that end, Blomstedt was intrigued by architecture theory and building standardization, for which he proposed a number of highly elaborate proportional systems based on musical harmonics, the best known of which was the so-called Canon 60.

One of his drawing analyses on harmonic proportions from 1973 was adopted as the logo of the Museum of Finnish Architecture.

Many of Blomstedt's theoretical writings were published in the journal Carré Bleu, which he had co-founded in Helsinki in 1958, with Finnish architects Keijo Petäjä and Reima Pietilä, Finnish architecture historian Kyösti Ålander, and French architect André Schimmerling, whom together formed the CIAM Helsinki group, the Finnish group associated with CIAM (Congrès Internationaux d'Architecture Moderne).
