'With regard to solar astronomy, the study of solar activity and of solar-terrestrial relations was at a peak at this period, and Greenwich was a world leader in the field. H.W. Newton (1893-1985) was in charge of the Solar Department; he stimulated Woolley's interest in this study, in both obtaining and interpreting observations. A large part of these came from the use of a Hale spectrohelioscope on loan since 1930 from Mt Wilson. Woolley and Newton constructed ancillary equipment that improved its performance. Woolley was able to interpret the results in terms of his theory of the structure of the solar atmosphere: he showed how the theory could be tested rather rigorously by the way in which the character of lines in the solar spectrum can be observed to vary across the solar disk, especially in the vicinity of the limb. This sort of observation was impossible except for the Sun. A highlight in this phase of Woolley's involvement in solar astronomy was his co-authorship of Eclipses of the Sun and Moon by F.W. Dyson and himself. Sir Frank Dyson (1868-1939), Astromoner Royal 1910-33, was an astronomer of great talent and remarkable versatility. Amongst his manifold astronomical activities, he had been a dedicated, successful and uniquely fortunate observer of total eclipses of the Sun. On his retirement he felt an obligation to write a book to review the scientific outcome of everything of the sort done hitherto. It was a typical inspiration on his part to invite so relatively young a colleague as Woolley to share in the work; he must have done so with the agreement of Spencer Jones as Woolley's Director. So far as I know. Woolley never saw a total solar eclipse, but he was able to provide a background of up-to-date solar physics, and incidentally to make the language of the text flow more smoothly than Dyson's more staccato style would have done. The result was an authentic classic of astronomical literature, though an unpretentious one' (William McCrea, 'Richard van der Riet Woolley 1906-1986', Australian Academy of Science, Biographical Memoirs of Deceased Fellows). 'The 1920s also brought the Astronomer Royal the opportunity to view his fifth eclipse. On June 29, 1927, thousands of people rushed to the North of England to witness the first total eclipse of the sun visible in this country for 200 years. In most areas, the skies were disappointingly overcast. But Sir Frank, who was renowned for his good luck with the weather on such occasions, picked the ideal location in the grounds of Giggleswick School, near Settle, in North Yorkshire. The total eclipse was due to occur just after 6am, and the sun remained hidden behind clouds until almost the last minute. Then, suddenly, the skies cleared to give the perfect view. The astronomer introduced a couple of innovations for recording the event. Not only was colour film used for the first time, but photographs were also taken from an aeroplane. Sir Frank Dyson finally retired as Astronomer Royal in February 1933, aged 65. . . . During his retirement, Sir Frank wrote a book on his favourite topic, in collaboration with fellow astronomer Richard van der Riet Woolley. Published in 1937, Eclipses of the Sun and Moon was considered an authoritative work on the subject' (Vivienne Smith, 'Sir Frank Dyson: Astronomer Royal was no pipsqueak', on You & Yesterday Web site).
