This question already has an answer here:
I have to add a
\supervisor field to the title page of my presentation. Is there a way to do that in beamer?
I tried adding the supervisor information to the
\author field, but the content of the author field are also displayed on the footer of all the slides, and I wanted just my name to be there. If adding a field is not possible is there
a way to display custom text at the footer?
