Overview: The Author Tag declares who is the author of the document

The author META tag defines the name of the author of the document being read. This tag is not widely supported but is recognized as part of the META Tag standard. Supported data formats include the name, email address of the webmaster, company name or Internet address (URL). The most common format is to insert the name of the person or organization and a contact email address. For example: Webmaster (webmaster@submitcorner.com)

Although not many search engines look specifically for the Author META tag, it clearly defines who is the author and/or the responsible party for making updates to the webpage(s).
