MAXWELL JAMES CLERK (b Edinburgh Scotland 13 June 1831 d Cambridge England 5 November 1879) Physics Maxwell was a descendant of the Clerks of Penicuik a family prominent in Edinburgh from 1670 on who had twice intermarried during the eighteenth century with the heiresses of the Maxwells of Middlebie illegitimate offspring of the eighth Lord Maxwell
