One of the largest and longest-running projects I’ve been working on as part of my research fellowship at Notre Dame and the Adler Planetarium has been Dioptrice, a database of surviving pre-1775 refracting telescopes. The brainchild of the former chief curator at the Adler, Dioptrice is the first step toward a richer history of the telescope: its origins, evolution, and diffusion as well as popular perceptions of the instrument in works of art and early books and manuscripts. The principle investigators of the project, which is funded by NSF and NEH grants, travel the world looking for early telescopes in museums and private collections. They analyze and photograph them and then send the data to me, where I add it to the database. I also scour catalogues and websites, initiate contact with additional collections, and search the rare book collection at the Adler for early telescope images. All of this goes into the database, which has been slowly building for the past few years.

Now it’s ready to go public. Information on hundreds of telescopes, fully searchable by year, type, maker, country of origin, and just about every other category you can think of. All hosted online in a sleek website designed by Parallactic Consulting but curated by yours truly. If you’re interested in the history of the telescope as art, artifact, or instrument, feel free to look around. If you know of telescopes that should be hosted here, let me know.

Have fun: www.dioptrice.com.


Update: I presented a poster on Dioptrice at the AAAS meeting in Chicago yesterday. ScienceNOW, the online AAAS science magazine, just published an article on the database, and I was featured as part of the #scienceWOW video series talking about William Herschel. (You can see all the videos, including one by Alan Alda, here.)
