William Watson (scientist)




In 1746 he showed that the capacity of the Leyden Jar could be increased by coating it inside and out with lead foil. In the same year he proposed that the two types of Electricity —vitreous and resinous—posited by DuFay were actually a surplus (a positive charge) and a deficiency (a negative charge) of a single fluid which he called ''electrical ether'', and that the quantity of electrical charge was conserved. (He acknowledged that the same theory had been independently developed at the same time by Benjamin Franklin —the two men later became allies in both scientific and political matters.)
