Heinz Isler (July 26, 1926 – June 20, 2009) was a Swiss structural engineer.
[1] He showed talent as an artist as a student, but his father advised him to seek a career in engineering first.
Isler studied thin concrete shells at the Federal Institute of Technology (ETH) in Zurich.
His first project as a shellbuilder was a concert hall roof for the Hotel Kreuz in Langenthal which was completed between 1954 and 1955.
The form of the shell was loosely inspired by the shape of a plumped-up pillow on his bed.
