Nicholas Saunderson lost his sight before he was twelve months old, yet he became professor of mathematics at Cambridge. He was an eminent authority in his day, an original and efficient teacher and the author of a book on algebra. His knowledge of optics was remarkable. “He had distinct ideas of perspective, of the projection of the sphere, and of the forms assumed by plane or solid figures.” D’Alembert was not only a mathematician but also a philosopher of the highest order. He was made a member of the French Academy at the age of twenty-four. He was so frail that his life was continually despaired of and he remained a valetudinarian to the end. IX STATESMEN AND POLITICIANS We now come to the statesmen and politicians. Robert Cecil, first Earl of Salisbury, Secretary of State under Queen Elizabeth and Lord Treasurer under James I, was a statesman who all his life wielded immense power to the undoubted benefit of his country. Yet in person he was in strange contrast to his rivals at court, being deformed and sickly. Elizabeth styled him her pigmy; his enemies vilified him as “wry-neck,” “crooked-back” and “splay-foot.” In Bacon’s essay “Of Deformity” he paints his cousin to the life. John Somers, Lord Keeper under William and Mary, “was in some respects” (I am quoting Macaulay) “the greatest man of his age. He was equally eminent as a jurist, as a politician and as a writer.... His humanity was the more remarkable because he received from nature a body such as is generally found united to a peevish and irritable mind. His life was one long malady; his nerves were weak; his complexion livid; his face prematurely wrinkled.” William III, I have already mentioned, and now comes a name to conjure with, the great Lord Clive, founder of the British Empire. At eighteen he went out to India and shortly afterwards the effect of the climate on his health began to show itself in those fits of depression during one of which he ended his life. We see in his end the result of physical suffering, of chronic disease which opium failed to abate. William Pitt, Earl of Chatham, one of the greatest statesmen England ever had, suffered from hereditary gout. The attacks continued from boyhood with increasing intensity to the close of his life. He was for two years mentally unbalanced, yet after that he returned to Parliament and directed for eight years all the power of his eloquence in favor of the American Colonies. Dr. Johnson said: “Walpole was a minister given by the King to the people, but Pitt was a minister given by the people to the King.”
