Abstract: |
The Swiss engineer Heinz Isler (1926-2009) was convinced that ‘formfinding is the most important factor in shell design’. The present contribution starts with an appreciation of his very first lecture at the founding colloquium of IASS in 1959; then it mentions the follow-up presentation 20 years later after an extremely active and successful period. His three main formfinding methods are discussed. Finally a short remark on the personality of Heinz Isler is given. |
