I’ll admit that I hadn’t heard of either Patricia or Fredrick McKissack by name, until I came across several newspaper obituaries, earlier today. Realizing only after that I own and use many of their books in my classroom. Many. Fredrick McKissack was the coauthor, and researcher of over a dozen non-fiction children’s books focused on the history of African-Americans. The above link will take you to the NY Times obituary of Frederick McKissack.
