Abstract: 
We summarise some of the substantial contributions of the late M.J.D. Powell to approximation theory and to optimisation, focusing specifically e.g. on uni- and multivariate splines (for instance Powell Sabin split), including radial basis functions, but also on optimisation methods for minimising functions without constraints, with and without using first derivative approximations, such as the famous DFP formula.
