Want to find articles about a specific author? Use the "Names as Subjects" tool.
Sometimes it's difficult to know exactly how an author's name will appear in articles about them - sometimes they'll have multiple accepted spellings of their names (such as Fodor Dostoevsky, whose name can be spelled Dostoyevsky, Dostoievski, Dostoevsky, Dostoyevski, Dostoevskii, Dostoevski, etc.), sometimes they'll write under more than one name (such as Stephen King, who also wrote under the name Richard Bachman), and sometimes they may have a name similar to a much more prominent writer that you don't want to research.
This is where MLA International Bibliography comes in handy - they have a standardized list of author names that they use for each of their articles. You can search these names and find articles written only about that particular person, regardless of how many spellings/pseudonyms/etc they have.

NOTE: MLA International Bibliography will automatically insert the Boolean operator "OR" between each of the names you check! If you want to search for articles about BOTH authors, you'll have to manually change the word "OR" in the search box (at the top of your results page) to "AND".
