[Brigadier-General](/source/Brigadier-General) **Walter Buckingham Caddell** (22 September 1879 – 20 April 1944) was a [Royal Artillery](/source/Royal_Artillery), [Royal Flying Corps](/source/Royal_Flying_Corps) and [Royal Air Force](/source/Royal_Air_Force) officer who served in a number of senior military aviation appointments during [World War I](/source/World_War_I).

Born on 22 September 1879, the son of Lieutenant-Colonel Henry Caddell and his wife Anna Matilda (née Persse), Walter Caddell was to grow up in a large family being the fourth child amongst nine children.[1]

He was commissioned a [Second lieutenant](/source/Second_lieutenant) in the [Royal Garrison Artillery](/source/Royal_Garrison_Artillery) on 26 May 1900, and promoted to the rank of [Lieutenant](/source/Lieutenant_(British_Army_and_Royal_Marines)) on 29 March 1902.[2]

In March 1916 Caddell was appointed Deputy Assistant Director of Military Aeronautics at the War Office in London. He effectively served as the chief assistant to Brigadier-General [Duncan MacInnes](/source/Duncan_Sayre_MacInnes), the Director of Aircraft Equipment.[3] It was in that capacity that he was introduced to [George Constantinescu](/source/George_Constantinescu) who had developed an experimental [synchronization gear](/source/Synchronization_gear).[4] With support from the Military Aeronautics Directorate, Constantinescu's synchronization gear was improved and deployed on aircraft in France.[5] [Archibald Low](/source/Archibald_Low) and the RFC [Experimental Works, Feltham](/source/R.F.C._World_War_I_Drone_Weapons) were under his command.[6] In April 1917 Caddell took over from an overworked and exhausted MacInnes as Director of Aircraft Equipment.[5][7] He retired from the RAF on 28 May 1919 with the honorary rank of brigadier-general.[5]
