Life of Sir Isaac Newton

SIR DAVID BREWSTER Life of Sir Isaac Newton Sir David Brewster, a distinguished physicist, was born at Jedburgh, on December 11, 1781. He was educated at Edinburgh University, and was licensed as a clergyman of the Church of Scotland by the Presbytery of Edinburgh. Nervousness in the pulpit compelled him to retire from clerical life and devote himself to scientific work, and in 1808 he became editor of the "Edinburgh Encyclopaedia." His chief scientific interest was optics, and he invented the kaleidoscope, and improved Wheatstone's stereoscope by introducing the divided lenses. In 1815 he was elected a member of the Royal Society, and, later, was awarded the Rumford gold and silver medals for his discoveries in the polarisation of light. In 1831 he was knighted. From 1859 he held the office of Principal of Edinburgh University until his death on February 10, 1868. The "Life of Sir Isaac Newton" appeared in 1831, when it was first published in Murray's "Family Library."
