William Thomson, 1. baron Kelvin
Vilijam Tomson, 1. baron Kelvin (; Belfast, 26. jun 1824 — Largs, 17. decembar 1907) je bio britanski teorijski fizičar, koji je razvio Džulovo shvatanje o pretvaranju toplote u mehanički rad. Pronašao je galvanometar sa ogledalom za primanje telegrafskih signala. U njegovu čast jedinica Međunarodnog sistema mera za temperaturu dobila je ime Kelvin (K). Npr. tačka mržnjenja vode 0 °C = 273 K.
