He held BA (1948) and PhD (1952) degrees from Cambridge. Chisholm developed a method for rational approximations of two variable functions generalising

Padé approximant In mathematics, a Padé approximant is the "best" approximation of a function near a specific point by a rational function of given order. Under this technique, the approximant's power series agrees with the power series of the function it is ap ...
