Remove author bio from posts of a specific author

In my theme with raw codes, Post Meta Data are shown like:

<div class="entry-meta">
   <span class="meta-prep meta-prep-author"><?php _e('By ', 'your-theme'); ?></span>
   <span class="author vcard"><a class="url fn n" href="https://wordpress.stackexchange.com/questions/110649/<?php echo get_author_posts_url( false, $authordata->ID, $authordata->user_nicename ); ?>" title="<?php printf( __( 'View all posts by %s', 'your-theme' ), $authordata->display_name ); ?>"><?php the_author(); ?></a></span>
</div><!-- .entry-meta -->

It displays the meta data like:

Post Content here like Lorem Ipsum is simply
dummy text of the printing and typesetting
industry.
____________________________________________
by Author_name

In my case, you can simply put a conditional tag like:

<?php if( !is_author( 'author_nickname' ) ) : ?>
   <div class="entry-meta">
      ...
   </div>
<?php endif; ?>

Note: I enabled the meta-box for all author, except someone. I put the author_nickname here, you can put the author_id too. Check the Codex:
