Category:Authors with missing birth dates

This is a maintenance category, added by a template to group pages for maintenance (non-navigation) purposes. It is automatically hidden on categorized pages.

These authors are missing birth dates. If these could be found, add them to the author template. Otherwise, if they are not believed to have a publicly known birth date, change the "birthyear" parameter to "?" to signify this, and the author will be categorised into Category:Authors with unknown birth dates instead.
