What's the correct use of \author when multiple authors?

Question

Working on a project, the article we are writing is written by me and someone else. How should I fill the \author?

What about \author{LASTNAME1, FIRSTNAME1 \& LASTNAME2, FIRSTNAME2}? It doesn't convince me, but it might be correct.

Is there any better way to do that?

P.S: I'm using the article class and the authors will be shown once with \maketitle{}.

Answer 1

The \maketitle command with \author allows a simple separation of two (or more) authors by using the \and command. See code below for some inspiration.

\documentclass[11pt,english]{article}
\usepackage[T1]{fontenc}
\usepackage{babel}

\author{
  LastName1, FirstName1\\
  \texttt{first1.last1@xxxxx.com}
  \and
  LastName2, FirstName2\\
  \texttt{first2.last2@xxxxx.com}
}
\title{Usage of the \texttt{\textbackslash author} command}

\begin{document}
  \maketitle
\end{document}
