Limit posts with a specific tag on the author page

I have been editing my author pages and want to limit the posts that show to all posts except those with the tag IDed 26. I have two possible loops – neither works quite right:

———————————–
Shows posts by 1 author but with all tags:
———————————–

<!-- The Loop -->

    <?php

    // The Loop
       if (have_posts()) : while (have_posts()) : the_post();
    ?>
            <li>
                <a href="<?php the_permalink(); ?>" rel="bookmark" title="<?php the_title(); ?>">
                <?php the_title(); ?></a>
            </li>

        <?php endwhile;
    else: ?>
            <p><?php _e('There are no recent posts by this author.'); ?></p>

        <?php endif; ?>

    <!-- End Loop -->

———————————–
Shows posts by all authors (not just the author who’s page we’re on) that are not tagged with ID 26
———————————–

<!-- The Loop -->

    <?php
    // The Query
     $args = array( "author=$curauth->ID", 'tag__not_in' => array( 26 ));
     $the_query = new WP_Query( $args );

    // The Loop
       if ($the_query->have_posts()) : while ($the_query->have_posts()) : $the_query->the_post();
    ?>
            <li>
                <a href="<?php the_permalink(); ?>" rel="bookmark" title="<?php the_title(); ?>">
                <?php the_title(); ?></a>
            </li>

        <?php endwhile;

    // Reset Post Data
    wp_reset_postdata();

    else: ?>
            <p><?php _e('There are no recent posts by this author.'); ?></p>

        <?php endif; ?>

    <!-- End Loop -->
