Author.php displaying posts from ALL authors.

Hi,

I’m trying to create custom author pages with two loops using author.php. I’m using two loops: the first to show the excerpt of the most recent post, the second to display a list of other posts.

My problem is that ALL authors posts are being displayed/listed. I would like only one.

Help please!
Example page: Craig on the Indie Travel Podcast

My code follows:

<?php
global $wp_query;
$curauth = $wp_query->get_queried_object();
?>

	<div id="content" class="narrowcolumn">

		<?php if (have_posts()) : ?>

		 <?php $post = $posts[0];  ?>
		<?php if (is_author()) { ?>
		<h2>Author profile: <?php echo $curauth->nickname; ?></h2>
		<?php
		$default = "https://indietravelpodcast.com/images/no_gravatar.jpg"; // link to your default avatar
		$size = 100; // size in pixels squared
		$grav_url = "https://www.gravatar.com/avatar.php?gravatar_id=" . md5(trim($curauth->user_email)) . "&default=" . urlencode($default) . "&size=" . $size;
		?>
		<a href="<?php echo $curauth->user_url; ?>"><img width="<?php echo $size; ?>" height="<?php echo $size; ?>" src="<?php echo $grav_url; ?>" alt="<?php echo $author_name; ?>" title="<?php echo $author_name; ?>" class="authorgravatar" /></a>

		<p class="authorprofile"><?php echo $curauth->description; ?></p>
		<?php } ?>

		<div class="clear"></div>

<!-- first loop -->
		<?php query_posts('showposts=1'); ?>
		<?php while (have_posts()) : the_post(); ?>

		<div class="post">
				<h2 id="post-<?php the_ID(); ?>"><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>">Most Recent: <?php the_title(); ?></a></h2>
				<small><?php the_time('l, F jS, Y') ?></small>

				<p><?php the_excerpt(); ?></p>

			</div>

		<?php endwhile; ?>
<!-- second loop -->
		<h2>More articles by <?php echo $curauth->nickname; ?></h2>
		  <?php rewind_posts(); ?>
		  <?php query_posts('showposts=10'); ?>

		  <?php while (have_posts()) : the_post(); ?>

			 <div>
			 <ul>
				<li><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title(); ?>"><?php the_title(); ?></a></li>
				<small><?php the_time('l, F jS, Y') ?></small>
			</ul>
			</div>

		  <?php endwhile; ?>

Thanks in advance!
