In America there has been a huge retrospective on the 50th anniversary of the moon landing. I'm not sure whether it's getting the same commemoration around the world, but here it's a big source of national pride. In 1901 Antonin Dvořák was a similar source of Czech national pride. For years this opera was performed almost exclusively for Czech audiences, leading to a perception in the rest of the world that Dvořák didn't write operas. Now it's one of his most famous pieces.
