Sir Isaac Newton

He was born December 25, the only child of Isaac Newton and Hannah Ayscough. The father died at thirty-seven, a few months after his marriage, and the young wife, after the birth of her child, was both father and mother to the helpless infant. He was so frail that there seemed little probability that he could live to manhood, or even boyhood. Naturally, between mother and son there grew a most ardent affection, which neither time nor death could change.
