# Customizing beamer title page?

And it looks like this as following:

My question is, I will be giving a presentation of a paper of other authors. So I want to add my name and university below the authors' universities but above the date, like this

University of author 1
my name
my university
date


with the same font size of showing authors' names and universities.

I know setbeamertemplate and addtobeamertemplate, but since it's a small modification, I am wondering is that possible to do this without redoing the whole template?

current code looks like this:

\documentclass{beamer}
\usetheme{Hannover}

\title{Presentation Title}

\subtitle{Optional Subtitle}

\author{F.~Author\inst{1} \and S.~Another\inst{2}}
\institute[Universities of Somewhere and Elsewhere] % (optional, but mostly needed)
{
\inst{1}%
University of Somewhere
\inst{2}%
University of Elsewhere}
\date{Conference Name, 2013}

% Let's get started
\begin{document}

\begin{frame}
\titlepage
\end{frame}
\end{document}

• @Cragfelt I was still editing. just added the current code. – Jason Hu Nov 21 '17 at 23:04

• @Cragfelt that's what I referred to. It's basically redefining the template, which is what I want to avoid, given this should be a small modification. – Jason Hu Nov 22 '17 at 0:36
• @Cragfelt unless your answer is "no, we must redefine template for any modificaiton". – Jason Hu Nov 22 '17 at 0:44

The clean solution is to redefine the title page template. This approach will give you all opportunities to fine tune the result to fit your needs.

\documentclass{beamer}
\usetheme{Hannover}

\title{Presentation Title}

\subtitle{Optional Subtitle}

\author{F.~Author\inst{1} \and S.~Another\inst{2}}
\institute[Universities of Somewhere and Elsewhere] % (optional, but mostly needed)
{
\inst{1}%
University of Somewhere
\inst{2}%
University of Elsewhere}
\date{Conference Name, 2013}

\makeatletter
\setbeamertemplate{title page}{
\vbox{}
\vfill
\begingroup
\centering
\begin{beamercolorbox}[sep=8pt,center]{title}
\usebeamerfont{title}\inserttitle\par%
\ifx\insertsubtitle\@empty%
\else%
\vskip0.25em%
{\usebeamerfont{subtitle}\usebeamercolor[fg]{subtitle}\insertsubtitle\par}%
\fi%
\end{beamercolorbox}%
\vskip1em\par
\begin{beamercolorbox}[sep=8pt,center]{author}
\usebeamerfont{author}\insertauthor
\end{beamercolorbox}
\begin{beamercolorbox}[sep=8pt,center]{institute}
\usebeamerfont{institute}\insertinstitute
\end{beamercolorbox}
% ----------------------- new
\begin{beamercolorbox}[sep=8pt,center]{author}
\usebeamerfont{author}my name
\end{beamercolorbox}
\begin{beamercolorbox}[sep=8pt,center]{institute}
\usebeamerfont{institute}my university
\end{beamercolorbox}
% ------------------------
\begin{beamercolorbox}[sep=8pt,center]{date}
\usebeamerfont{date}\insertdate
\end{beamercolorbox}\vskip0.5em
{\usebeamercolor[fg]{titlegraphic}\inserttitlegraphic\par}
\endgroup
\vfill
}
\makeatother

\begin{document}

\begin{frame}

\end{document}


However on your on risk and with the warning that this is a) a dirty hack and b) might cause problems with the pdf properties if you don't give a short institute which can even render some pdf viewers unable to open your pdf - be warned!
