# Same affiliation for all authors without extra packages

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 most simple solution (which is not to say it is the best) is not to use \and.

\documentclass{article}
\title{Foo}
\begin{document}
\maketitle
\end{document}

That's really most simple. (+1) –  Thorsten Donig Feb 21 '11 at 18:17

At the moment I see no other solution than using e. g. the authblk package. For details please refer to the package manual.

\documentclass[11pt,a4paper,english]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{authblk}
\usepackage{blindtext}

\title{Two Authors with same Affiliation}
\author{Author One}
\author{Author Two}
\affil{Affiliation}

\begin{document}
\maketitle

\blinddocument
\end{document}

The blindtext package is only for creating dummy text thus not part of the solution
