howto show category name by ID

Hallo!

I just want to show the name of my category with the ID=1
within my template. So I tried:

<h2><?php echo( get_category( 1 ) ); ?></h2>

But that gives me the following error:

Catchable fatal error: Object of class stdClass could not be converted to string in …

I understand that get_category delivers in the wrong format but have no clue what to do to get the screen printout of the name.

any help appreciated,
thx,
