Bob Metcalfe was working at Xerox PARC in 1973 when he invented Ethernet, a standard for connecting computers together over short distances. In 1979, Metcalfe departed PARC and founded 3Com, a manufacturer of computer networking equipment.
The son of Thomas and Elizabeth Metcalfe, Bob was born at Rishton in 1896.
Bob survived the fateful day unscathed, and was promoted to Acting Lance Corporal two weeks later as the battalion returned to the trenches in the Neuve Chapelle sector.
The severity of Bob's wounds is evident from his transfer to the 25th (Garrison Guard) Battalion, The King's (Liverpool Regiment) on 24th April 1918, the battalion being largely composed of men who were considered unfit for active service either because of age or owing to poor health.
