Galton, Francis (1822-1911)
English statistician and meteorologist who, in a letter to the London Times, on Aug. 6, 1892, proposed using a combination of mirrors to reflect sunlight toward Mars in order that it might be detected by any Martian astronomers with the aid of telescopes. This was similar to an earlier idea put forward by Cros in France. It stimulated a lively debate in England on (a) the likelihood of there being intelligent life on Mars and other neighboring worlds (including the Moon), and (b) the merits of trying to send signals. One of those who opposed the scheme was Richard Hutton.
