In memoriam.

Michael Elliott, 83, who developed the first synthetic pyrethroid and was instrumental in revolutionizing modern insecticides.

In the 1940s Elliott recognized that the pyrethrins, chemical compounds which occur naturally in chrysanthemum flowers, had important insecticidal qualities, although they lacked potency and stability and were not specific in the insects they killed.

While working at the Rothamsted Experimental Station at Harpenden, Hertfordshire, he embarked on a program to develop synthetic analogues of the naturally occurring compounds and developed two, resmethrin (1962) and bioresmethrin (1967) which were more potent than their natural equivalents and targeted specific insect species, while being harmless to mammals and birds.
