William Herdman Hall (16 August 1901 â 20 October 1983) was an Irish international rugby union player.
Born in Belfast, Hall was rugby captain for his final year at Royal Belfast Academical Institution and then became a foundation player for Instonians, winning back to back Ulster Senior Cups in 1922 and 1923.
Hall gained six Ireland caps as a fly-half, debuting against England at Leicester in 1923. The following year, Hall formed with John McDowell an all-Instonians Ireland halfback combination for a match against France.
