Black Female Playwrights - Part I

After seeing The River Crosses River II, I began putting together a list of black female playwrights that I am familiar with. Then I began to search the web for more names. Now, I am pretty sure that I have missed many, but in no particular order, here is my initial attempt. Can you tell who they are...

I will disclose who they are in the coming days...
