Ernest Elliott Markwick: variable stars and military campaigns

Colonel E.E. Markwick, CB, CBE, FRAS (1853 - 1925) pursued a distinguished career in the British Army, serving in Great Britain and other parts of the Empire and rising to the rank of Colonel. He was an original member of the BAA and went on to become President between 1912 and 1914. His main observational interest was the study of variable stars and he independently discovered two variables, RY Sgr and T Cen. He directed the BAA Variable Star Section from 1899 to 1909, organising its work along lines that are largely pursued even to this day and which other variable star organisations around the world have emulated.

💡 Research Summary

Ernest Elliott Markwick (1853‑1925) was a distinguished British Army officer who simultaneously pursued a passionate career in amateur astronomy, becoming one of the most influential figures in the early development of variable‑star observing. Born in Kent and educated at King’s College School, he entered the Army’s Control (later Ordnance) Department in 1872. His first overseas postings took him to southern Africa, where the clear, dry skies of the Transvaal and Bechuanaland offered an unrivalled view of the southern heavens. Markwick’s letters from the field describe the “Milky Way, Zodiacal Light and Clouds of Magellan” and record precise naked‑eye observations of Mercury, Venus and occasional comets. These experiences sparked a lifelong fascination with variable stars.

In 1874, on his 21st birthday, he received a 2¾‑inch refractor, the instrument that would accompany him throughout his military career. He supplemented it with a pair of 1½‑inch binoculars and, despite the cumbersome “pillar‑and‑claw” mount, he fashioned a homemade altazimuth tripod and later an equatorial mount, eventually building a small roll‑off‑roof observatory at Devonport with the permission of the War Office. His modest equipment proved sufficient to discover two new variables: RY Sagittarii, a rare R Coronae Borealis‑type star, and T Centauri, a southern‑hemisphere eclipsing system. Both discoveries were made independently of professional surveys and added valuable entries to the rapidly expanding variable‑star catalogues of the late 19th century.

Markwick’s most lasting contribution was organisational. In 1899 he succeeded William H. Steavenson as Director of the British Astronomical Association’s Variable Star Section (VSS), a post he held until 1909. He introduced a systematic programme that required observers to use the same comparison stars, to keep detailed nightly logs, and to submit their results on a regular schedule. He instituted a quarterly “Report” that collated observations, calculated periods, and published revised ephemerides. This framework, remarkably similar to the modern AAVSO model, ensured data consistency across a geographically dispersed network of amateurs and laid the groundwork for international cooperation.

Beyond the VSS, Markwick was an active member of the Royal Astronomical Society (elected 1879), the Liverpool Astronomical Society, and a founding member of the British Astronomical Association (BAA) in 1890. He wrote the popular introductory article “Naked‑Eye Astronomy” for the JBAA, aiming to make the subject accessible to newcomers, especially women, and he gave public talks to soldiers in Gibraltar, encouraging them to keep night watches that could double as astronomical observations. His attempts at popularisation were tempered by the class consciousness of the Victorian era; he recognised that most rank‑and‑file soldiers would view astronomy as a “caviar to the general” but still highlighted occasional enthusiastic participants.

When the First World War broke out, Markwick, then a retired colonel, volunteered for service and was appointed Assistant Director of Ordnance Stores in Dublin. Although his wartime duties limited his personal observing time, he remained BAA President from 1912 to 1914, delivering presidential addresses that stressed the Association’s “Mission” and the importance of scientific work even in wartime. His 1914 address, read by the Astronomer‑Royal F. W. Dyson, emphasized loyalty to country while expressing hope that the Association could continue to serve astronomy after the conflict.

After the war Markwick retired to Boscombe, later moving to West Moors, where he continued observing with an 8½‑inch Alta‑Zimuth reflector and a 4‑inch Grubb refractor. He was honoured with a CBE in 1919 for his valuable war service.

Markwick’s legacy can be summarised in three interlocking strands: (1) the creation of a robust, repeatable observing programme that became the template for modern variable‑star networks; (2) the discovery of two significant variables, demonstrating how an amateur with modest equipment and a global posting could contribute to frontier research; and (3) a commitment to outreach and education, seeking to bring astronomy to soldiers, women, and the general public despite prevailing social hierarchies. His organisational principles—standardised comparison stars, regular reporting, and collaborative data analysis—remain at the heart of contemporary citizen‑science projects. In this way, Ernest Elliott Markwick stands as a bridge between the disciplined world of the British Army and the collaborative, inclusive spirit of modern amateur astronomy.
