Another approach could be to use a function that loops through [`get_posts`][1] and prints the result.

Check this Q&A: http://wordpress.stackexchange.com/q/1753/12615

    // function located in the theme's functions.php
    function wpse_78117_print_authors_last_post() 
    {
    	$user_ids = array( '1', '2' );
    	foreach( $user_ids as $user )
    	{
    		$args = array( 
    				'post_type'     => 'post',
    				'numberposts'   => 1,
    				'author'		=> $user
    			); 
    		
    		// as we are getting only 1 post, extract it from the returned array
    		$user_post = array_shift( get_posts( $args ) );
    		
    		// similar
    		$nick = array_shift( get_user_meta( $user, 'nickname' ) );
    
    		// custom output, $user_post contains all the post normal data
    		echo $user_post->post_title . ', by: ' . $nick;
    	}
    }

And then use it in any theme template:  
`<?php wpse_78117_print_authors_last_post(); ?>`.
