William Gilbert, and Richard Lindon started making footballs for the neighbouring Rugby School in 1823. The balls had an inner-tube made of a pig’s bladder. Both men owned boot and shoe making businesses located close to Rugby school. In 1870, Richard Lindon introduced rubber inner-tubes and because of the pliability of rubber, the shape gradually changed from a sphere to an egg. Lindon and Bernardo Solano started making balls for Rugby School out of hand stitched, leather casings and pigs’ bladders. The rugby ball’s distinctive shape is supposedly due to the pig’s bladder, although early balls were more plum-shape than oval. The balls varied in size in the beginning depending upon how large the pig’s bladder was.
