Charles Watson-Wentworth, second marquess of Rockingham, F. R. S. (1730-1782): some aspects of his scientific interests
'I cannot but wish that our nation abounded with more frequent examples of persons, of like rank and ability with your lordship, equally desirious of promoting . . . every other branch of natural science that lends to the honour and benefit of our country.’ So James Bradley, a member of the Council of the Royal Society addressed the Earl of Macclesfield, P. R. S. from 1752-1764. Bradley’s wish, so like Sprat’s of nearly ninety years before, was realized in the person of the second Marquess of Rockingham, elected F. R. S. at the age of 21 on 7 November 1751, who died on 1 June 1782 at the early age of fifty-two. Hitherto, attention has been concentrated on the political aspects of Rockingham’s career. This is not unnatural since Rockingham was twice prime minister: at the age of thirty-five and also at his death. He was an outstanding advocate of proposals to grant independence to the American colonies, and a champion of those who suffered under the crippling disabilities of the Test Acts. His only biographer, Lord Albemarle, ransacked Rockingham’s papers to print a rechauffé of letters concerned entirely with the political kaleidoscope of the eventful thirty years in which his subject played such a leading role (2). Subsequent historians have either been bemused by the towering personality of Burke and tended to regard Rockingham as Burke’s patron, or have been so intent in unravelling the complicated structure of patronage and political connexion in the age of George III that Rockingham has appeared as just another Whig (3). * Numbers in parentheses refer to the numbered notes at the end of this paper.
