With the death of Hans Piepho, international entomology has lost one of its last pioneers from the first period of insect endocrinology. During this period, insect endocrinology established itself as a discipline despite the dogma that hormones are restricted to vertebrates. This dogma stemmed from a long, futile search for sex hormones in invertebrates, mainly in insects, which had led only to negative results [Bockmann 1989: references]. Indeed, up to the present time no real sex hormones like those of vertebrates, which are produced by the gonads and determine the development of secondary sex characters, have been found in other phyla.
