Here are two ways you can achieve something like this. First, you can use the multicol package, and do this:
\documentclass{article}
\usepackage[]{hyperref}
\usepackage{multicol}
\begin{document}
\noindent{\LARGE Albert Einstein}\\[1cm]
\begin{multicols}{2}
\noindent Institute for Advanced Study
\vfill
Einstein Drive\\
Princeton, N.J. \texttt{08540}
U.S.A.
\columnbreak
\noindent Phone: \texttt{609-734-8000}\\
Fax: \texttt{609-924-8399}\\[.2cm]
email: \href{mailto:a.einstein@ias.edu}{a.einstein@ias.edu}\\
\textsc{url}: \href{http://www.ias.edu/spfeatures/einstein/}{http://www.ias.edu/spfeatures/einstein/}
\end{multicols}
\end{document}
Another way would be using two parboxes or minipages whose width is exactly of
the width of the text. In this case you do not need any additional packages.
\vspace{1in}
\noindent{\LARGE Albert Einstein}\\[1cm]
\parbox[b]{.5\hsize}{
\noindent Institute for Advanced Study\\
Einstein Drive\\
Princeton, N.J. \texttt{08540}
U.S.A.}%
\parbox[b]{.5\hsize}{
Phone: \texttt{609-734-8000}\\
Fax: \texttt{609-924-8399}\\[.2cm]
email: \href{mailto:a.einstein@ias.edu}{a.einstein@ias.edu}\\
\textsc{url}: \href{http://www.ias.edu/spfeatures/einstein/}{http://www.ias.edu/spfeatures/einstein/}
}
Notice that in both cases, the vertical spacing between lines is an issue, you
have to manually tune the spacing so that the lines will come up "alligned".
I don't know if there is any way LaTeX can do this automatically for you, but
it can be done with ConTeXt, which supports typesetting on a grid.
