Bert Spencer

Updated: 1/9/2024

Bert Spencer has been an enigmatic figure within steam locomotive engineering history. Very little has been widely known about his life other than the work he did under Sir Nigel Gresley . He was very introverted and took none of the limelight for himself, leaving it all to Gresley. He was the Conjugated Valve Gear specialist on Gresley's engineering team. He was a primary participant in Gresley's pacific projects being responsible for such important features as the Corridor tender and the introduction of long lap valves to the A1s onward.

Thankfully a biography about him has finally been published (12th September 2023). You can purchase the biography Gresley's Master Engineer, Bert Spencer here .
