[rete] SIC Neuchatel - call for session papers - calculating machines in observatories

[Louise Devoy]

Dear colleagues,

Greetings from Greenwich. Following the recent acquisition of a Brunsviga calculating machine formerly used in the Royal Observatory’s Nautical Almanac Office, I am interested in learning more about the general use of calculating machines in observatories, from their early adoption in the late 19th century through to the age of computers.

 
I would like to propose a themed session on ‘Calculating Machines in Observatories’ for SIC Neuchâtel to address questions such as:
• Were these machines bespoke or simply off-the-shelf purchases? Did this vary for different purposes and projects?
• Was there any interaction, co-development or feedback with the manufacturers?
• Were certain brands preferred?
• How were they incorporated into the Observatory’s routine and who was permitted to use them?
• How did observatory directors and staff react to the new technology?
• What were the advantages and challenges of their use?
• How did their adoption affect the quality and output of ephemerides?

In addition, I would also welcome oral presentations based on recollections and reflections of your lived experience of working with these machines.

If you’d like to join me, please do get in touch via lde...@rmg.co.uk by 13 February 2026, thank you.

All best wishes,

Louise
