Hi there, Peter! Nice to see you again. 🙂
The nice thing is that Events posts already support the default Author functionality provided by WordPress. That means you can override the template where you would like to display the Author and use the following in the template:
<?php $author = get_the_author(); ?>
While this sort of customization is certainly possible, we’ll leave it to you to make it happen. You can check out our Themer’s Guide for more information on overriding templates (including a full list of available templates to override). The WordPress Codex has more information on using the get_the_author() function.
I hope this helps!
Geoff
