Family scrapbook recording Broadbent's career for Grubb Parsons, including photographs, official documents (including travel passes) and handwritten explanatory notes by Broadbent [and a son/daughter]. It covers:

1. Broadbent's 1938 visit to Mount 'Pop Ivan', Poland, and the opening day of the Observatory there. Broadbent had designed the dome and telescope there and was sent by Grubb Parsons to complete the telescope mounting. He personally did the electrical wiring and fitted the optical lenses.

2. Broadbent's work assembling the PZT (Photographic Zenith Tube) at Neuchatel, 1954. Includes a press photograph of Broadbent at work, photographs of the PZT, 'PZT house' and team, and a brochure for the Jaquet-Droz automatons of the Neuchâtel Museum complete with samples of writing and drawing made by them. See also RGO 113/4/4.

3. Broadbent's 1963 visit to Switzerland to design a new reflecting telescope for the Sphinx Observatory, Jungfraujoch (note, postcard and brochure).

4. Personal accounts of his professional interactions with Sir Frank Dyson, Sir Howard Spencer Jones, Sir Richard Woolley and Professors Sampson and Greeves.
