In 1621 the Mayflower set sail. I heard it was a rough ride.
But as for teacherninjas, it was the birthday, in 1856, of Booker T. Washington! There are a million biographies of him and his own work to check out, but the kid's book everyone seems to like is a fictionalized but inspirational story of him working in a salt mine and desperately learning to read. More Than Anything Else by Marie Bradby, illustrated by Chris Soenpiet.
"The longer I live and the more experience I have of the world, the more I am convinced that, after all, the one thing that is most worth living for-and dying for, if need be-is the opportunity of making someone else more happy."
-Booker T. Washington
