According to John Latschar, superintendent of Gettysburg National Military Park, the architects hired during the Mission 66 program "ran amok." The Mission 66 program implemented under Eisenhower produced, in addition to Neutra's Cyclorama Center, the Gateway Arch in St. Louis by Eero Saarinen.
The LA Times ran an article yesterday by Mark Rozzo entitled Who Chooses History?
The National Park Service Has Decided That L.A. Architect Richard Neutra's Landmark Cyclorama Center--Which Has Stood at the Gettysburg Battlefield for More Than 40 Years--Now Detracts From the History.
Richard Neutra's son Dion, who is also an architect, is fighting the impending demolition of the "Abraham Lincoln Shrine of the Nation." Besides running amok, the other great quote from the LA Times article is this one from Mr. Latschar, "Mr. Neutra had the idea that this would be his monument to Lincoln and freedom and all that stuff." Yeah, why bother with all that stuff?
