Two 'maketitle's in article

Question

I'm writing a report with two parts using the article class.

\documentclass[a4paper,11pt]{article}
\usepackage[T1]{fontenc}

\usepackage[english]{babel}
\usepackage{amsmath,amsfonts,amsthm}
\usepackage[pdftex]{graphicx}   
\usepackage[top=1in,bottom=1in,left=1in,right=1in]{geometry}
\usepackage{sectsty}
\allsectionsfont{\centering \normalfont\scshape}
\usepackage{fancyhdr}

\title{\huge Title1 \\}
\author{\normalfont                 \normalsize
    Author\\                        \normalsize
    Supervisors: Prof. X}
\date{}

\begin{document}

\part{Heisenberg Picture}

\maketitle

\section{Section 1}


\clearpage

\part{Schroedinger Picture}

%\maketitle2

\section{Section 1}

\end{document}

I need two parts titled say, \part{Heisenberg Picture} and \part{Schroedinger Picture}. These parts correspond to Title 1,Supervisor X and Title 2,Supervisor Y respectively. How can I redefine the \maketitle command to do this? (If it's too complicated, is there an easier method?)

Answer 1

The titling package does exactly what you require. I've also cleaned up your code to put the formatting parts into the \pretitle etc. commands leaving the contents of \title and author free of formatting.

\documentclass[a4paper,11pt]{article}
\usepackage{titling}
\pretitle{\begin{center}\huge}
\posttitle{\par\end{center}\vspace{\baselineskip}}
\preauthor{\normalfont\normalsize\begin{center}\begin{tabular}[t]{c}}
\postauthor{\end{tabular}\end{center}\vspace{\baselineskip}}

\title{Title 1}
\author{Author\\Supervisors: Prof. X}
\date{}

\begin{document}

\part{Heisenberg Picture}

\maketitle

\section{Section 1}

\clearpage

\part{Schroedinger Picture}
\title{Title 2}
\author{Author\\Supervisors: Prof Y}
\maketitle

\section{Section 1}

\end{document}
