John C. Butcher
John Charles Butcher  (born 31 March 1933) is a New Zealand mathematician who specialises in numerical methods for the solution of ordinary differential equations. Butcher works on multistage methods for initial value problems, such as Runge-Kutta and general linear methods. The Butcher group and the Butcher tableau are named after him. More recently, he is investigating a new type of method with stability identical to that of a Runge-Kutta method. Biography

Butcher studied mathematics at Auckland University College - BSc and MSc  - and the University of Sydney - PhD (1961) and DSc. Positions held are as aside. He was awarded the Jones Medal from the Royal Society of New Zealand in 2010, for his "exceptional lifetime work on numerical methods for the solution of differential equations and leadership in the development of New Zealand mathematical sciences." In 2011, he received the Van Wijngaarden Award. In the 2013 Queen's Birthday Honours, Butcher was appointed an Officer of the New Zealand Order of Merit, for services to mathematics. Publications
