Henry Cabourn Pocklington FRS (28 January 1870, Exeter – 15 May 1952, Leeds) was an English physicist and mathematician. His primary profession was as a schoolmaster, but he made important contributions to number theory with the discovery of Pocklington's primality test in 1914{{Cite web |url=http://services.spd.dcu.ie/johnbcos/download/3rd_year/Pocklington_1914/1914_PAP1.html |title=Pocklington's test |access-date=2007-02-08 |archive-url=https://web.archive.org/web/20070207005132/http://services.spd.dcu.ie/johnbcos/download/3rd_year/Pocklington_1914/1914_PAP1.html |archive-date=2007-02-07 |url-status=dead }} and the invention of Pocklington's algorithm. He also derived the first equation for the current in a wire antenna, Pocklington's integral equation.{{cite journal
