Raymond Langford Scholarship in Ecology and Evolutionary Biology

Raymond R. LangfordRaymond Langford was born in Norham, Ontario, in 1908. He studiedunder professor Rawson, Canada's foremost limnologist of the time and receivedhis BSc from the University of Saskatchewan in 1932. Ray Langford received hisPhD in 1936 for his research on the distribution and utilization of limneticcrustacea in Lake Nipissing, and this seminal study continues to be cited. Dr.Langford was appointed lecture in 1936, rose to the rank of Professor andserved as Associate Chair for fourteen years. Professor Langford's first lovewas teaching, especially introductory zoology, which he taught every year from1933 to 1976.

Ray Langford shifted his research toLake Opeongo, where he pioneered in several aspects of qualitative limnology,such as the measurement of light penetration in lakes, the spectral compositionat depth and the biomass of plankton in lakes. He undertook a study of theeffects of chemical fertilization of small unproductive lakes in AlgonquinPark.

In 1944. Dr. Langford was the biologist in charge of an investigationinto the effects of forest spraying with DDT. His report on the lethalconsequences of DDT on fish, amphibians, crayfish and aquatic insects was oneof the earliest undertaken anywhere. In 1951 Professor Langford experimentedwith the neutralization of acid lakes using powdered limestone, a processadopted for anthropogenically acidified lakes a quarter century later. TheHarkness Laboratory on Opeongo was the mecca for limnological research in the1930s and 1940s and Professor Langford was Director of the lab from 1946 to1957.

Ray's hobby was painting, most especially scenes of Algonquin Park.

Thanksto a very generous donation by Dr. Robert W. Langford, there is now anundergraduate award honoring the late Professor "Ray" Langford.
