Professor John Lennox Monteith FRS FRSE
John Lennox Monteith, who has died aged 82, pioneered the application of physical principles in the study of how plants and animals interact with their immediate environment, or microclimate. In a career spanning over half a century, he is perhaps best known for the Penman-Monteith equation that has become the basis for guidelines for estimating irrigation water requirements used by the FAO (Food and Agriculture Organization of the United Nations).

He became one of the youngest ever Fellows of the Royal Society of London in 1971, and was made a Fellow of the Royal Society of Edinburgh in 1972. In addition he was a Fellow (1951) and Honorary Fellow (1997) of the Royal Meteorological Society, Fellow (1966) of the Institute of Physics, Fellow (1976) of the Institute of Biology, and served as president of the Royal Meteorological Society from 1978 to 1980. In 1989 he was awarded an honorary DSc by the University of Edinburgh. During his career he served on many national and international scientific committees and on the editorial boards of prominent scientific publications. He also served as Fellowship Secretary to this Society from 1997-1999.
