Harvard College Observatory History in Images

This is a personal project collecting and documenting early images of Harvard College Observatory, focusing on the site at Observatory Hill (previously Summer House Hill). Buildings, instruments, people, and observations.

Disclaimer: all content here is solely my own views, and in no way represents the views of my employer, or anyone else. Also, I'm documenting things as I learn about them, so expect frequent errors. Corrections will occur without notice and without a changelog at this point.
