How do I find out what fonts are used in a document/picture?

I wonder what font is used in this article ?
I've used WhatTheFont but can't find the result.
And Fond Finder tells me that it's Trump Mediaeval, but they are slightly different.(If you look at m.)

Answer 1

The used fonts can be displayed e.g. using pdffonts:

$ pdffonts schmidt.pdf 
name                                 type              emb sub uni object ID

It looks to me it uses the mathpazo package/font.

Answer 2

It's Palatino, actually URW Palladio; the math fonts are from MathPaZo.

\usepackage{mathpazo}
