posts per page -1 not working

Hi,
I’m trying to NOT limit the number of posts per page (I want to show all posts). I set up the query like so, setting posts_per_page to -1

<?php query_posts(‘author=1&posts_per_page=-1’); ?>

But it still paginates it to 14 posts per page.

very important: I’m not trying to change the preference for the whole site, I know you can do that in the preferences. I’m only trying to change one perticular page
