Heinz Isler (July 26, 1926 – June 20, 2009) was a Swiss structural engineer. He is famous for his thin concrete shells.
Heinz Isler was born in the municipality of Zollikon. 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.
Upon graduating from the ETH in 1950 with a degree in civil engineering, Isler worked as a teaching assistant with Pierre Lardy, a professor at the ETH, from 1951 to 1953. He opened his own office in 1954 in Burgdorf, Switzerland. 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.
Isler died from a stroke on June 20, 2009 at the age of 82.
