David Peakall

David Peakall, English chemist and toxicologist (b. 1931)
David Beaumont Peakall (17 March 1931 – 18 August 2001) was an internationally recognised toxicologist. His research into the effects of DDE and DDT on eggshells contributed to the ban on DDT in the United States. He proved that the chemicals caused thinning of eggshells, leading to a reduction in the population of various bird species. He also pioneered research on the effects of PCBs on birds.
