Landing Gear Development

Following on from Creaking Door’s non aviation quiz.
Does anybody know who first coined the phrase(or patented) the Oleo/Pneumatic strut for a/c landing gear.

A bit of googling has revealed some early aircraft with some form of oil/air landing gear strut.

Breguet appeared to have something similar in 1911.

T S Duncan of Vickers patented some form of this type in 1915.

Not sure there is an easy answer to this one:rolleyes:
