There are several recent articles in major magazines discussing the construction of the Modern Philosophy canon. Each notes the philosophical contributions of figures that have been largely overlooked, however influential they were in their own time. Here are the links:
"Descartes is Not Our Father," by Christia Mercer, is in the New York Times
"Who was that Marquise? Rediscovering Forgotten Voices of Women in Philosophy," by Andrew Janiak, is in the Washington Post.
