How to use Views to make a Block that displays a field from the author's profile? using Drupal 7.

I have added a field in the user account settings called "author summary" (field_author_summary)

When a user is editing their profile, they can enter a brief description of themselves into this field.

Now, the goal is to display this information as a block, directly under the content they are the author of.

I can't figure out the proper contextual filters and/or relationships.

Any ideas?

Thanks!\
