Cardinal Nicholas de Cusa

Died 11 Aug 1464 (born 1401). German theologian, influential philosopher, mathematician, and scientist. His scientific ideas, shrouded in theological language, were his personal speculations. Before Copernicus by half a century, he suggested that the Earth was a nearly spherical shape, turned on its axis and revolved around the Sun (1440); that each star is itself a distant sun with inhabited worlds in orbit; and that space was infinite. In mathematics, he contributed concepts of the infinitesimal and of relative motion. He made spectacles for nearsighted people using concave lenses, departing from the usual and more easily produced convex shape that worked only for farsighted users. He considered air as a source of some sustenance for plants, and recognized the pulse for diagnosis.
