text: Born in 1906 in Bristol, England, the oldest of seven children of an Irish father and English mother, the family soon settled in Ireland where he spent his youth. From 1919 to 1924 he attended the CBS Sexton Street secondary school in Limerick City. The school had no science program, but Nevin was interested in physics and managed to learn the subject pretty thoroughly on his own. In 1924 he got a scholarship to University College Dublin, where he excelled in mathematics and physics, winning first-class honours every year, and earning an honours B.Sc. in Experimental Physics and Mathematics in 1927. He got his M.Sc. under J.J. Nolan in 1928 for a treatise on "The Effect of Water Vapour on the Diffusion Coefficients and Mobilities of Ions in the Air". That year he was also awarded an 1851 Research Fellowship, which enabled him to study spectroscopy at Imperial College, London (1929–1931). In 1931, he returned to Dublin to continue his research and was appointed an assistant in the department of experimental physics.
  In 1940, he was awarded a D.Sc. degree at National University of Ireland for previously published work, and in 1942, he was awarded an honorary doctorate at Queens University Belfast. Throughout the 1930s and 1940s he continued his research in molecular spectroscopy, often working with research groups in fundamental particle and cosmic ray physics. He was a capable administrator at UCD, serving on the universitys finance and buildings committees, as well as the academic council and governing body, and he initiated many improvements to the physics department. When J. J. Nolan died in 1952, Nevin succeeded him as Professor of Experimental Physics, a position he held until his retirement in 1979.
  Nevin was a strong advocate for expansion of the UCD campus, which for half a century was based at Earlsfort Terrace in the city. As a key member of UCD's academic council and a member of its buildings committee (1957–76), he was instrumental in moving the science faculty to the new Belfield campus in the southern suburbs in 1964.
  He was a key figure in the formation of the Irish branch of Institute of Physics.
  At the Dublin Institute for Advanced Studies he was a member of the governing boards of the school of theoretical physics (1943-1961) and the school of cosmic physics (1948-1956).
  On 16 March 1942 he was elected a member of the Royal Irish Academy and served on its council from 1944 to 1968.
