He was educated at St Cyprian's School in Eastbourne, Eton and Magdalene College, Cambridge.

He served in the army during World War II and was awarded the T.D. After the war he began farming in Buckinghamshire. He retained his military connections and became Lieutenant-Colonel in 1947 and was commanding officer of the 16th Airborne Division Signals Regiment (Middlesex Yeomanry) (Territorial Army) in 1948.^[1] He became Honorary Colonel of the 16th (later 40th) Signal Regiment in 1957 and its successor, the 47th (Middlesex Yeomanry) Signal Regiment, in 1962.^{[citation needed]}

Capell married, firstly, Mary Reeve Ward, daughter of F. Gibson Ward, on 2 March 1937. They were divorced in 1957. His second wife was Nona Isabel Miller (1906–1997), daughter of David Wilson Miller and widow of Francis Sydney Smythe of Yew tree cottage in November 1957. He had no children by either marriage.^{[1] [4]} In 1967, Debrett's had identified Bladen Horace Capell, "a grocery clerk in Yuba City, California" as the person eligible to become the Earl of Essex, if no other heirs could be identified.^[5]

On his death in 1981, the title became dormant, but it was revived eight years later by a distant cousin, Robert Capell.^[4]
