 On 25 Nov 1816, Lewis Morris Rutherfurd was born, an American astrophysicist and spectroscopist who made the first telescopes designed for celestial photography. He produced a classification scheme of stars based on their spectra as similarly developed by the Italian astronomer. Rutherfurd spent his life working in his own observatory, built in 1856, where he photographed (from 1858) the Moon, Jupiter, Saturn, the Sun, and stars down to the fifth magnitude. While using photography to map star clusters, he devised a new micrometer to measure distances between stars with improved accuracy. When Rutherford began (1862) spectroscopic studies, he devised highly sophisticated diffraction gratings. The Obituary of Lewis Morris Rutherfurd gives a full account of his life and accomplishments. |

 Charles Kettering (1876-1958) was an American engineer who held 140 patents for his many inventions. As vice president and director of research for General Motors Corp. (1920-47) he developed engines, quick-drying lacquer finishes, anti-knock fuels, and variable-speed transmissions. He provided intermission talks during the radio program General Motors Symphony of the Air. A collection of his scripts (1942-45) are on this site, with an index of Short Stories and Science and Invention. Although some are dated, they remain of historical interest, and together, it is interesting to know how the listeners could tune in to intelligent radio programs in that era, and how a prolific inventor could communicate with the general public. |

| Quotations for Today | |
 | Being the inventor of sex would seem to be a sufficient distinction for a creature just barely large enough to be seen by the naked eye. [Comment about Volvox, a freshwater green algae, which appears indetermimately plantlike and animal-like during its reproductive cycle.] - Joseph Wood Krutch, American naturalist, conservationist and conservationist (born 25 Nov 1893).  |
| Science is not, as so many seem to think, something apart, which has to do with telescopes, retorts, and test-tubes, and especially with nasty smells, but it is a way of searching out by observation, trial and classification; whether the phenomena investigated be the outcome of human activities, or of the more direct workings of nature's laws. Its methods admit of nothing untidy or slip-shod; its keynote is accuracy and its goal is truth. - Archibald Garrod, English physician and biochemist (born 25 Nov 1857). | |
 | Science is founded on uncertainty. Each time we learn something new and surprising, the astonishment comes with the realization that we were wrong before. - Lewis Thomas, American physician and author (born 25 Nov 1913). |
