multiple authors and affiliations

[andreas-h]

Hi, first of all, let me thank for this document, it's very helpful!

Can you elaborate on how to include multiple authors with multiple affiliations? When I just repeat the \Institute command twice, only the second gets printed to the PDF, the first is ignored.

How can I have more than one affiliation?

Hello, glad it's of some use -- for others than just me.

Your question is, in fact, a pure Beamer question; you should first see how to answer it "the Beamer way". Here's one link found by Google: https://tex.stackexchange.com/questions/17961/how-to-add-several-authors-with-different-affiliations-in-beamer.

Hi, thanks a lot for taking the time to answer :-)

While I agree that it's mostly a LaTeX / Beamer question, using it in Ord doesn't just work:

#+TITLE: Title goes here
#+AUTHOR: Author1 \inst{1} \and Author2 \inst{2} \and Author3 \inst{3}
#+LATEX_HEADER: \institute[shortinst]{\inst{1} Affil1 \and \inst{2} Affil2 \and \inst{3} Affil3}
#+LaTeX_CLASS: beamer
#+LaTeX_CLASS_OPTIONS: [presentation,smaller]
#+BEAMER_THEME: default

  Hello

doesn't work when I export with C-C C-E l P.

The problem seems to be that Org includes the \inst in the pdfauthor attribute in the call to \hypersetup:

When I remove the \hypersetup command, I can compile the resulting TeX without problems.
