W. Elst at the European Southern Observatory. William Thomson (Lord Kelvin, 1824-1907), well known for the absolute temperature scale, contributed to modern physics through his major role in the development of the second law of thermodynamics. His theoretical work on submarine telegraphy led to the laying of the first transatlantic cable.
