A 2006 merger of The Dallas Museum of Natural History, The Science Place and the Dallas Children’s Museum formed one museum — the Museum of Nature & Science.

Ross Perot’s children made the $50 million gift that got the new home along Woodall Rodgers underway.

The museum opens today.

Arnold Wayne Jones took a first look here.
