Gulielmus Thomson, primus baro Kelvin (natus die 26 Iunii 1824 in oppido Belfast; mortuus die 17 Decembris 1907), physicus mathematicus et ingeniarius Britannicus, hodie praeclarissimus est non solum quia gradus temperaturae absolutae invenit[1] sed etiam quia analysim mathematicam scientiarum electromagneticae et thermodynamicae saeculi 19 maxime ingreditur.

Anno 1851 priscam formam secundae legis thermodynamicae his verbis statuit:

Non est possibile, nisi facultas immaterialis intercedit, phaenomenon mechanicae derivare e cuiusquam materiae parte quam frigescimus sub frigidissima tempuratura corporum circumpositorum.[2]

Suis cum Iacobo Ioule operis de caloris natura annos 1852-1856 theoriam kineticam caloris magnopere statuit.[3] Annos 1855-1856 Thomson quoque cum Petro Guthrie Tait collaboravit et scripsit suorum magnum "Detractatus de Philosophia Naturali" qui novam disciplinam physicae unificabat sub sententia energiae.[4]
