NPL News – Creator of the moving coil watt balance passes away

In memory of Dr Bryan Kibble, 1938-2016

Dr Kibble worked at the National Physical Laboratory (NPL) from 1967 to 1998 as an experimental physicist. He was instrumental in reshaping the International System of Units (SI), and is best known for his conception of the watt balance, one of the measurement approaches proposed for the redefinition of the kilogram. Dr Kibble will be dearly missed by the international measurement community, with former colleagues citing his quiet and patient guidance, and praising his problem-solving skills.
