Horace Walter Rigden

He worked as a laboratory assistant and after the outbreak of the First World War joined the Royal Flying Corps on 19 August 1915 where he served as an Air Mechanic 2nd Class.

His advanced education was delayed by the war and he enrolled at the University of London, graduating in 1922 with a Bachelor of Science degree.

[3] Rigden was employed by The Anglo-Persian Oil Company Limited in Abadan, Iran, which eventually became British Petroleum.

Rigden married Frances Helena Shilling (born 12 July 1903) on 20 Mar 1926 at All Saints Church, Whitstable.

Their daughter Jill Allibone, who was born at Abadan in 1932 (died 1998), was a distinguished architectural historian who founded The Mausolea and Monuments Trust.
