Today in History: March 28

A still from the Soviet animated film.
Sixty-nine years ago today, on March 28, 1944, Astrid Lindgren sprained her ankle in Sweden and began writing "Pippi Longstocking," the book that made her a beloved children's author. But it was a subsequent book, "Karlsson on the Roof," that made her a Soviet hit. The book, called "The World's Best Karlsson" in Russian, has been published in about 60 different editions, mostly without permission, and an animated Soviet film was a huge success. During a trip to Sweden in 1997, President Boris Yeltsin apologized to Lindgren for the Soviet-era piracy.
