Louis Jourdan wrote in USMA 12393: >United Kingdom : 9 > Michael Faraday (1791-1867) > Stephen Gray (1666-1736) That can't be right. Radiation therapy was unknown in the 18th century. Henri Moreau in his "Le Syst�me M�trique" of 1975 on page 85 says "L. H. Gray (English physicist, 1905 - 1965)". Moreau also attributes the weber to Wilhelm Eduard Weber, 1804 - 1891. His biography in the Encyclopaedia Britannica, supports that theory. Joseph B. Reid 17 Glebe Road West Toronto M5P 1C8 Tel. 416 486-6071
