1896 Obituary 
WILLIAM CHARLES STIFF was born at Leamington on 1st September 1836.
He was at one time engaged at The Brades Steel Works near Birmingham; and commenced his engineering work in 1863, and since that time had been engaged in designing and manufacturing machinery for making gun-barrels and cold-drawn weldless steel-tubes.
In this direction he began by experimenting upon some original machinery for the manufacture of weldless steel-tubes, which had been abandoned as useless; and by his energy and ability the difficulties connected with the process were ultimately surmounted, and cold-drawn weldless steel-tubes, now so extensively used for cycles and for boilers of torpedo boats and their destroyers, were successfully manufactured and introduced.
He established the Credenda Seamless Steel-Tube Works at Smethwick, near Birmingham, of which he was the managing director.
His death took place at his residence in Edgbaston, Birmingham, from syncope, on 6th June 1896, in his sixtieth year.
He became a Member of this Institution in 1888.
