Pioneers in Chemical Ecology
Thomas Eisner (1929-2011)
Most biologists today are familiar with only a handful of model organisms, and more as fancy reagents than as organisms that need to solve real-world problems. Tom incorporated all of the latest advances in physics and analytical chemistry to make his natural history discoveries more understandable, more approachable; he had a knack for keeping his research going forward into the digital revolution without losing track of the analogue world that is our natural history legacy.

Dietrich Schneider (1919-2008)
One of the pioneers of modern olfactory research, he was the first to use electrophysiology to investigate the sense of smell, by directly recording the responses of single sensory neurons to the odour stimulus. His success depended crucially on his choice of the silk moth as experimental animal, because its males are very sensitive to the sexual attractant released by the females — as by now not only experts in the field but also every educated layman knows. This proved to be a model system for olfaction.

Jeffrey Harborne (1928-2002)
Jeffrey Harborne made a major contribution to the development of phytochemistry in the second half of the twentieth century, not only in terms of his original research in the area of anthocyanins and chemical ecology but also in his thorough and scholarly documentation of work on natural products...
In his research he collected together a considerable amount of data on the role of flavonoids in insect–plant interactions and he examined the relationship between anthocyanins and pollination ecology.

Ernst Stahl (1858-1919)
Stahl was among the first scientists who performed experiments in ecology which is best illustrated by his studies on the defenses of plants against herbivores...
He observed great variation in the efficiency of the various defenses against the different herbivores he studied, and he marveled at the rich diversity of mechanically and chemically mediated defenses in plants...
Stahl recognized that many morphological structures of vegetative and reproductive plant organs are understandable only from the point of view of plant–animal interactions, for instance, the relationship of flower shape to pollinators.
