Authorlist including biographie

Hello,

I’m trying to build an author page where ervery author is displayed.

I used this tutorial:

https://www.scottbressler.com/blog/2011/03/wordpress-archive-page-with-all-authors-and-all-posts

This works perfect, but I want to display the bio information for all authors, too.

<?php echo $author->description; ?>
This don’t work.

Can you please help me?
