In June 2006 the Science Museum was merged with the Dallas Children's Museum and the Natural History Museum to form a single entity, the Museum of Science and Nature. On December 1, 2012 the MSN will be reopened in downtown Dallas as the Perot Museum of Nature and Science, leaving the original buildings in Fair Park abandoned and empty for the first time since 1936. This web page contains historic information featuring the Science Museum as it existed prior to its move to downtown Dallas.
