# Problems with middle name

In my literature directory it only shows the first and last name, but I want to see the middle name as well. My codes is:

\documentclass[a4paper,12pt]{article}
\bibliographystyle{chicago}
\begin{document}
\bibliography{BIB}
\end{document}


And in my bibfile:

@phdthesis {RK,
title={{R}unge-{K}utta Methods for Stochastic Differential Equations},
author={Burrage, {P.M.}},
year={1999},
school={The University of Queensland, Brisbane}
}


I want that it lookks like:

Burrage, P. M. (1999). Runge-Kutta...

but it looks like:

Burrage, P. (1999). Runge-Kutta...

How can I change that?

You are missing a space in the first name(s), so BibTeX only 'sees' one: try {Burrage, P. M.} – Joseph Wright Dec 13 '13 at 14:47
