William Herdman Hall (16 August 1901 — 20 October 1983) was an Irish international rugby union player.[1]
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.[2]
Hall gained six Ireland caps as a fly-half, debuting against England at Leicester in 1923.[3] The following year, Hall formed with John McDowell an all-Instonians Ireland halfback combination for a match against France.[2]
