Today on Anita Silvey’s Children’s Book-A-Day Almanac there’s a review of Ballet for Martha: Making Appalachian Spring. From that review — as well as from today’s Google Doodle — one learns that today, May 11, is Martha Graham’s birthday. Happy birthday to her! Thanks to Anita for the thoughtful, generous, and well-timed review. You can read it here, and if you scroll down to the comments you’ll find a link posted by Sandra Jordan (co-author with Jan Greenberg of Ballet) that will lead you to the story behind today’s Google animation — a collaboration (again with the collaboration!) between Google and the Martha Graham dance company.
