earlier. Although this proposal was rejected it did lead to closer co-operation between the two institutions. Tedder became an authority on a number of topics within the field of chemistry, and was the author or co-author of some 200 technical essays and several textbooks. One of his areas of expertise concerned organofluorine chemistry, and he pioneered the use of gas-liquid chromatography at Sheffield University in the 1950s. He composed a number of technical papers on the reactivity of orthoquinones. He developed a two-stage ion-beam spectrometer. He was also recognised by his peers as an important authority in free radical chemistry. In addition to his distinguished work in chemistry, Tedder succeeded his father as baron and served in the House of Lords. Although he was apparently reluctant to perpetuate the title, he was persuaded by colleagues that the peerage system could benefit by the presence of a scientist and educator. He served on the House of Lords Committee on Hazardous Waste, and contributed to discussions in the House about matters of science and tertiary education. In 1968 he was elected a Fellow of the Royal Society of Edinburgh. His proposers were Sir Edmund Hirst, Peter Pauson, Ralph Raphael, D. W. A. Sharp, Neil Campbell, Manfred Gordon, Patrick Dunbar Ritchie and Thomas Stevens Stevens. In 1981, Tedder became a founding member of the World Cultural Council. Tedder maintained a lively interest in the Royal Air Force and attended many honorary functions related to the squadrons in which his father had served. He also followed in his father's steps in his deep reading about Oliver Cromwell, and had planned to write a book on Cromwell. Tedder was also interested in classical music and played the piano. Near the end of his life he developed Parkinson's disease (the same affliction from which his father died). He then developed Alzheimer's disease, which forced him into retirement, and he was eventually placed in permanent nursing care until his death in 1994. Family Tedder was married to Peggy Eileen Growcott, and they were the parents of two sons and a daughter. The elder son, Robin John Tedder (born 1955), is now the 3rd Baron Tedder and Master of Wine; the younger son is Andrew Tedder.
