Invention Timeline - Lewis Morris Rutherford, American Physicist; Discovered the Use of the Star-Spectroscope to Show the Exact State of Achromatic Correction in an Object Glass, Particularly for the Rays Used in Photography
b. November 25, 1816 and d. ?
American physicist. He discovered the use of the star-spectroscope to show the exact state of achromatic correction in an object glass, particularly for the rays used in photography. He constructed a micrometer for the measurement of astronomical photographs, for use upon pictures of solar eclipses or transits, and upon groups of stars. His photographs of the moon have not been surpassed. He constructed a ruling engine in 1870 that produced interference-gratings on glass and speculum metal.
What is glory? What is fame?
The echo of a long-lost name;
A breath; an idle hour’s brief talk;
The shadow of an arrant naught;
A flower that blossoms for a day,
Dying next morrow;
A stream that hurries on its way,
Singing of sorrow;
The last drop of a bootless shower,
Shed on a sear and leafless bower;
A rose stuck in a dead man’s breast,-
This is the world’s fame at the best!
—William Motherwell
1765, March 7-1833, July 5—Joseph Nicephore Niepce lived. He first discovered the transient images of the camera-obscura. His process he termed “Heliography.” He invented the “Pyreolophore” and other apparatus.
