[Tex/LaTex] Same affiliation for all authors without extra packages

affiliationtitles

I have a working paper with a colleague from the same institution, so we entered:

\author{A B \and C d}

how can I now add affiliation, so that its for both authors (centred), and not only for one of them? I would prefer not to use extra packages if possible.

The simplest solution (which is not to say it is the best) is not to use \and.

\documentclass{article}
\title{Foo}
\author{Author One\qquad Author Two\\Affiliation}
\begin{document}
\maketitle
\end{document}
