Does anyone know how to display the authors details / about me (Biography, Location, Interests, Occupation ) in a post?

I have tried various solutions such as:

<?php echo $vbulletin->userinfo['location'] ?><br />
<?php the_author_ID(); ?>
<?php the_author_meta(); ?>
<?php the_author_description(); ?>

but no luck

I am desperate to find how to do this and have't had much success googling or searching for it.
