David Peakall

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. Peakall was born in Purley, Surrey, England and lived in Coulsdon, Surrey, as a boy. He demonstrated a keen interest in ornithology as well as chemistry, which led him to work as a volunteer at the RSPB reserve at Minsmere. He received a Ph.D. in Physical Chemistry in 1956 from the University of London, and a D.Sc. from Oxford University in 1979...
