Ken Leffew and George Lahm Named DuPont Fellows

DuPont Central Research & Development and DuPont Crop Protection Research & Development have named Ken Leffew and George Lahm as DuPont Fellows in recognition of their sustained contributions to DuPont over their careers.

In his 34 years with DuPont, Ken has led diverse product and process developments ranging from a novel polymerization route for polyester to new fluoropolymers for use as photoresists and membranes for direct methanol fuel cell applications. Ken is the coauthor of the reference book “Control of Polymerization Reactors”, and has received numerous external and internal awards, including four Engineering Excellence Awards.

George, with 26 years of DuPont service, discovered Crop Protection’s proprietary anthranilic diamide class of insecticides, and led the chemistry optimization effort that yielded two commercial development candidates, including Rynaxypyr™, which will be commercialized in 2008. George is a past recipient of the Bolton-Carothers Award, the prestigious American Chemical Society Award for Team Innovation, and the Pedersen Award for his role in the discovery of indoxacarb, sold under the trade names of Steward® insecticide and Avaunt® insecticide.

The position of DuPont Fellow is the highest level of technical professional leadership in the company. “The DuPont Fellows represent our finest technical minds and I am pleased to see Ken and George join this prestigious group,” said DuPont Senior Vice President and Chief Science & Technology Officer Uma Chowdhry.
