Besides what we know about his contribution to machine tools he invented a hexagon shaped round for field guns, In test this went 25 miles, 4 times further than anythink going at the time including the armstong gun which was adopted by the British forces and cause the cock up at Crimea where we were under enemy gun fire before we could fire.
if we had thave used the whitworth gun the whole think would never have happened.
Just because armstong was better represented in parliment, nothing changes
And then to add insult to ingury the Yanks 'invented' the hexagon round back in the 1980's
