Andrew Ronald Mitchell
Introduction


**Andrew Ronald Mitchell** (22 June 1921 – 22 November 2007\) was a [British](/wiki/British_people "British people") [applied mathematician](/wiki/Applied_mathematics "Applied mathematics") and [numerical analyst](/wiki/Numerical_analysis "Numerical analysis"). He was a professor of mathematics at the [University of St Andrews](/wiki/University_of_St_Andrews "University of St Andrews"), [Dundee](/wiki/Dundee "Dundee"), Scotland. He was known for his contributions to the field of [numerical analysis](/wiki/Numerical_analysis "Numerical analysis") of [partial differential equations](/wiki/Partial_differential_equation "Partial differential equation") in general and [finite difference method](/wiki/Finite_difference_method "Finite difference method") and [finite element method](/wiki/Finite_element_method "Finite element method") in particular. Mitchell has authored several influential books on numerical solution of partial differential equations, including "The Finite Element Analysis in Partial Differential Equations" with Richard Wait and "The Finite Difference Method in Partial Differential Equations" with David F. Griffiths.
