Object Details
- Holcomb, Amasa
- Description
- Amasa Holcomb (1787-1875) was a self-taught astronomer, surveyor and photographer, and the first American to make telescopes for sale. In 1833, the American Journal of Science reported that he "manufactures spy glasses of every description now in use; also achromatic telescopes of forty eight inches focal length” and "reflecting telescopes of from eight to twelve feet focal length." The Franklin Institute in Philadelphia reported that Holcomb’s reflecting telescopes compared favorably with instruments imported from Europe at much greater cost.
- This may be the larger of the two Holcomb instruments that were examined by a committee of the Franklin Institute on May 4, 1835, and that led to the recommendation that Holcomb be awarded the Scott's premium. It has an 8-inch mirror made of speculum metal, a sheet metal tube, and a Newtonian mount. It remained in the attic of the family home in Southwick, Mass., until 1933, when a descendant of the maker offered it to the Smithsonian.
