| biography:
| Physicist, born in London, UK. A telegrapher by training, he had to retire because of deafness in 1874, and spent much of his life investigating electricity. He predicted the existence of an ionized gaseous layer (the ionosphere) capable of reflecting radio waves, at the same time as, but independently of, the American Arthur E Kennelly, and made important contributions to the theory of electrical communications. |
