Chappis was a keen ski tourer exploring the mountains around Grenoble in the 1930s before joining the army and serving in the early stages of World War II.
His ideas were often controversial, especially with developers more concerned with profits than aesthetics.
This led him to be nicknamed the Anarchitecte.
In the 1960s he was appointed as a United Nations expert on mountain development.
A nomination that came not from his native France but from Italy.
Chappis is also credited along with the architect Denis Pradelle with creating a modern, functional style of mountain architecture which rejected both traditional Savoie styles and the Tyrolean chalet style of architecture.
