BRAGG WILLIAM HENRY: (1862-1942) English Physicist, Chemist & Mathematician, Nobel Prize winner for Physics, 1915. T.L.S., W H Bragg, one page, 4to, Albemarle Street, London, 13th February 1929, to A. W. Isenthal, on the printed stationery of the Davy Faraday Research Laboratory at The Royal Institution. Bragg thanks his correspondent for their letter and information and continues to make a clarification, 'I am sure that Sir Arthur Schuster when he told me his little storey (sic) about Rontgen did not mean to imply that Rontgen had been rude only that Rontgen seemed to think he had been. If I gave any other impression, I am very sorry'. Some light creasing and a few tears to the edges, none of which affect the text or signature. G Arthur Schuster (1851-1934) German-born British Physicist. Wilhelm Rontgen (1845-1923) German Physicist, discoverer of X-rays and winner of the inaugural Nobel Prize in Physics, 1901.
