The BIPM announces the death of Dr W.R Blevin

It is with sadness that we pass on the news that Dr W.R. Blevin passed away on 11 August 2022.

Bill was for many years an active participant in the CIPM’s Consultative Committee for Photometry and Radiometry (CCPR). He played a key role in preparing the redefinition of the candela by the CGPM in 1979, and co-authored the BIPM guidebook “Principles Governing Photometry”. He was a member of the International Committee for Weights and Measures (CIPM) for eighteen years, served as CCPR President from 1982 to 1994, CIPM Vice-President from 1992 until 1997, and CIPM Secretary from 1997 until 2000. He was the main author of the “Blevin report” submitted by the CIPM to the 21st General Conference on Weights and Measures in 1999: “National and International Needs relating to Metrology: International Collaborations and the role of the BIPM”.

During the course of his career he held positions as the chair of the National Standards Commission, CSIRO’s Chief Standards Scientist, and Chief of the CSIRO Division of Applied Physics.

Bill was aged 92 and passed away peacefully, surrounded by his family.
