John Nye

John Frederick Nye (26 February 1923 – 8 January 2019) was a British physicist and glaciologist. He was the first to apply plasticity to understand glacier flow. Career His early work was on the physics of plasticity, spanning ice rheology, ice flow mechanics, laboratory ice flow measurements, glacier surges, meltwater penetration in ice, and response of glaciers and ice sheets to seasonal and climatic changes. Later in his long career, he worked extensively in optics, publishing his last paper on electromagnetic wave polarization only a few days before his death. He was elected a Fellow of the Royal Society in 1976. He served as president of the International Glaciological Society (1966–9), who awarded him the Seligman Crystal in 1969 for outstanding contributions to glaciology. He was also president of the International Commission of Snow and Ice of the International Association of Hydrological Sciences (1971–5). The Cryosphere Focus Group of the American Geophysical Union hosts a Nye Lecture each year at its fall meeting. Awards and recognition Nye won the Chree medal and prize in 1989. He was Emeritus Professor in Physics at the University of Bristol, UK. In addition to glaciology, his research interests included caustics and microwave probes.
