How to display "About the author" tab in article display page?
There is Author Pane


  Author Pane is a block of information about a given user, like those
  typically found on a forum post, but can be used in other places as
  well. From core, it collects the user picture, name, join date, online
  status, contact link, and profile information. In addition, any module
  or theme can feed it more information via the preprocess system. All
  of this information is then gathered and displayed using a template
  file.


For the tabbed view you cold try Quick Tabs


  The Quick Tabs module allows you to create blocks of tabbed content,
  specifically views, blocks, nodes* and other quicktabs*.
