Cadeby Official Promoted
Major Herbert Williamson (formerly of the K.O.Y.L.I.), assistant engineer of the Denaby and Cadeby collieries, has been appointed chief engineer by the Staveley Coal and Iron company, and takes up his duties almost immediately.
Major Williamson,who is 35 years of age, was educated at the Doncaster grammar school, and has acquired practically the whole of his engineering experience at the Denaby and Cadeby collieries, where he has been under the tutelage of his father, Mr Ralph Williamson, engineer in chief at the collieries.
He distinguished himself in the Cadeby disaster (July 1912), and was awarded the Edward medal of the second class for gallantry and coolness in helping to restore some brick stoppings which had been blown out by a third explosion.
Before the war. Major Williamson held a commission in the fifth (territorial) Battalion of the K.O.Y.L.I..
He went to the front in April 1915, and served continuously in France until demobilised early this year. Latterly he was attached the machine gun Corps.
His promotion in the service was unusually rapid.
The news of this preferment to the important Staveley post will be welcomed in the Conisborough district, where Major Williamson is very popular.
