- Description
- This was made by Robert Stanton Avery, Jr., a mathematician who spent a long career computing tide tables for the U.S. Coast Survey, and who gave the Smithsonian Institution a substantial sum of money to be used for the “extension of the sciences.”
- We know that Avery made several telescopes in the early 1850s, while working on the family farm in Connecticut. This example has a brass barrel 24½ inches long that measures 4¾ inches diameter at the large end and 1½ inches at the small end. The lenses are lacking.
