# Multiple affiliations of an author in sig-alternate

I am trying to put two affiliations for an author in sig-alternate (ACM SIG Proceedings), for the second author. So effectively, the second author should be over both the second and the third affiliations. But there is no way I can keep the third author field blank and have only the affiliation there. Is there any other way to do this?

\author{
\alignauthor
First Author\\
\email{somemail@someserver.edu}
\alignauthor
Second Author\\
\email{otheremail@company.com}
\alignauthor
Test author\\
\email{larst@affiliation.org}
}

Welcome to TeX.sx! It's not clear what you're for; should "Second author" be above both affiliations? – egreg Mar 7 '13 at 18:08
Thanks! Yes, second author will have two affiliations. – Abhishek Chanda Mar 7 '13 at 18:45

For two authors I'd go with \and rather than \alignauthor, using a nested tabular for the two affiliations:

\documentclass{sig-alternate}

\begin{document}

\title{Paper}

\author{%
First Author\\
\email{somemail@someserver.edu}
\and
Second Author\\
\begin{tabular}[t]{@{}c@{}}
\email{otheremail@company.com}
\begin{tabular}[t]{@{}c@{}}
\email{larst@affiliation.org}
\end{tabular}
}
\maketitle

\end{document}

That is perfect! Thanks – Abhishek Chanda Mar 12 '13 at 23:31
Thanks for this great proposal! It's the only answer that I found so far that doesn't really violate the template enforced by a conference. If there are not many authors (thus no space problem) this solution is just great! – dim_tz Sep 3 '15 at 11:02
is it possible to do such a simple elegant tabular solution with \author for multiple authors all with a shared affiliation? with acmsiggraph, where this one seemed to work fine. – antont Jun 5 at 18:22
@antont Not sure what you mean. – egreg Jun 5 at 19:06
@egreg well what said there: how to have multiple authors with a shared affiliation? I've tried the solution in that answer but no success, tex.stackexchange.com/questions/271627/… . The one here works but for a different purpose (here many affiliations for single author, i'd need a single affiliation block under the names of all the authors) – antont Jun 6 at 8:03
