The redefinition of the SI in November 2018 — •Terry Quinn — 92 rue Brancas, 92310 Sevres, France

The redefinition of the SI on 16th November 2018 by the 26th General Conference on Weights and Measures, marked the final achievement of the grand idea set out by Laplace, Lagrange, Condorcet Monge and Borda on 19th March 1791 for a system of units belonging to no one country, linked to no particular place and accessible to all. My talk will trace the story of how this happened.
