The Swiss engineer Heinz Isler (1926-2009) was convinced that “formfinding is the most important factor in shell design” [7]. 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. Isler’s aversion against computer models is briefly mentioned. Finally a short remark on the personality of Heinz Isler is given.
