# For authblk package, how to correctly separate authors?

Update: Problem solved. See my own answer below. Credit to Werner.

I am using authblk package for an article. The authors can not be separated correctly. Here is the MWE:

\documentclass[twocolumn, twoside]{article}

\usepackage{authblk}
\usepackage{multicol}
\usepackage{fancyhdr}

\begin{document}

\begin{multicols}{1}
\title{\fontsize{24pt}{10pt}\selectfont\textbf{The Title Here\\}\vspace{1ex}}

\author[1]{Author One}
\author[2]{Author Two}
\author[1,2]{Author Three}
\author[3]{Author Four}

\affil[1]{\small University of California;}
\affil[2]{University of Missouri;}
\affil[3]{University of Maine}
\renewcommand\Authsep{, }
\renewcommand\Authands{, and }

\date{}

\end{multicols}

\twocolumn[
\maketitle
\thispagestyle{fancy}
\begin{abstract}
{\fontfamily{pnc}\selectfont

\textbf{Abstract:} Following the first case series of Hodgkin lymphomas
}
\end{abstract}
]

\section{Introduction}

Although Pathology is as ancient as 17th century BC Egyptian medicine, Hematopathology can only be historically traced back to 1832 AD when Thomas

\end{document}


The authors appear as:

I wish it would be Author One^1, Author Two^2, Author Three^1,2, and Author Four^3. Why Authsep{, } and Authands{, and } commands do not work?

Thanks for suggestions.

• I am not getting the output you mention under the article document class. So you must be doing something different. Could you supply the community with a minimal working example (MWE)? – Werner Dec 21 '15 at 6:37
• No. We don't need an entire bibliography since it has nothing to do with the problem. Keep it minimal. Click the link I provided to see what is meant by a MWE. Remove all the unnecessary stuff while still being able to replicate the problem. – Werner Dec 21 '15 at 7:00
• @Werner -Excellent suggestion! I found out the problem: it is due to the \begin{multicols}{1} and \end{multicols}. After removing them, the authors are separated as expected. – TeXIQ Dec 21 '15 at 7:37

With the help from Werner, I figured out the problem: it is due to the \begin{multicols}{1} and \end{multicols} that are flanking the author and affiliation portion. Removing multicols fixed the problem (see the correct result in the photo).
