Heikki Hyytiainen
Heikki Hyytiainen -- 1938 - 2018

We are sad to report that Heikki Hyytianinen passed away on May 13. Heiikki was a Finnish architect who apprenticed under Alvar Aalto, and was responsible for re-establishing masonry heater construction and use in Finland. I attended a workshop in 1981 organized by Maine Wood Heat Co., where Heiiki taught us how to build Finnish contraflow heaters, and changed my career path. We were fortunate to have Heikki attend Wildacres in 2017.
The photo was sent by his daughter Helena, and shows Heikki at an Aalto exhibit last August.
