'''George Birch Jerrard''' (25 November 1804 &ndash; 23 November 1863) was a British [[mathematician]].

He studied at [[Trinity College, Dublin]] from 1821 to 1827.  His main work was on the [[theory of equations]], where he was reluctant to accept the validity of the work of [[Niels Henrik Abel]] on the insolubility of the [[quintic equation]] by [[Nth root|radical]]s.  He found a way of using [[Tschirnhaus transformation]]s to eliminate three of the terms in an equation, which generalised work of [[Erland Samuel Bring|Erland Bring]] (1736–1798), and is now called [[Bring–Jerrard normal form]].
