Lieutenant Leonard Monteagle Barlow MC & Two Bars (5 June 1898 – 5 February 1918) was a British World War I flying ace.
He was born in Islington, London and studied electrical engineering prior to joining the Royal Flying Corps.
Dubbed 'The Gadget King', due to his inventiveness, Barlow developed an ingenious way of firing both of his SE5a aircraft's machine guns at the same time.
On 5 February 1918, Barlow was killed at Martlesham Heath whilst test flying a Sopwith Dolphin which broke up in mid air.
He is buried at Bandon Hill Cemetery, Plot F.85[1] For conspicuous gallantry and devotion to duty when engaged in aerial combats.
