Welcome to historical letters from Sydney Observatory

The letterbooks

The documents presented in this blog are copies – mostly of letters written by Sydney Observatory Government Astronomers. One or more is being posted every day for a year in an ‘on this day’ format from 5 June 2008 – the date Sydney Observatory turns 150.

These document copies are from bound letter books kindly lent by State Records of NSW. This research project furthers our understanding about the development of Sydney Observatory and its key role in the scientific history of New South Wales.
