How to put a footnote in the title in LyX

Question

I would like an unmarked footnote in my title. When I enter the footnote in the title, it does not appear in my PDF. How can I insert an unmarked footnote in the title which appears on the bottom of the first page?

MWE:

\documentclass[english,reqno]{amsart}
\usepackage[T1]{fontenc}
\usepackage[latin9]{inputenc}
\usepackage{amsthm}

\makeatletter
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Textclass specific LaTeX commands.
\numberwithin{figure}{section}

\makeatother

\usepackage{babel}
\begin{document}

\title{{\normalsize{}}\thanks{ABC}{\normalsize{}Title}}\maketitle

\end{document}

Answer 1

If you want a unmarked footnote in the first page, do not use a LyX footnote within the title ( = \thanks{}) but a \footnotetext{} in a ERT box. It can work better (i.e., wihout small caps) after the \maketitle in the first line of the normal text environment.

To avoid the mark (0 in this case) you can \let\thefootnote\relax (i.e, \thefootnote do nothing) but only for this \footnotetext if you want normal footnotes after that. See Footnote without a marker for another ways.

LaTeX version:

\documentclass[oneside,english]{amsart}
\usepackage[paperwidth=15cm,paperheight=6cm]{geometry}
\usepackage{amsthm}
\begin{document}
\title{My AMSART Title}
\maketitle
{\let\thefootnote\relax\footnotetext{This is my unmarked footnote.}}
My article text.%
\footnote{A marked footnote.}
\end{document}
