By the numbers

I am a new employee at the National Museum of American History. In fact, at the time of this writing, I have been working here for 9 weeks, 3 days, and 16 hours. Each morning I ride the elevator up 5 floors, walk past 36 doors, and work for approximately 8 hours. The numbers alone may not say it, but I work at a great place! Every day for the last 9 weeks, 3 days, and 14 hours, I have come to work and learned something new about the museum, the collections, and American history. At home “did you know?” has become a catch phrase for me.

3600_06_LG For example, did you know that in 1914, during the first major conservation effort for the Star-Spangled Banner, 11 needlewomen attached a linen backing to the giant flag with approximately 1.7 million hand sewn stitches? And did you know that in 2001, during the second major conservation effort, conservators painstakingly removed those 1.7 million stitches in order to detach that same linen backing? Now, I’m not a numbers person—I studied history because I love stories—but sometimes numbers tell an incredible story: 1.7 million stitches, twice!

For the reopening of the museum we have gathered a few facts and numbers. If you take a few minutes to look over these numbers, I think you will find they tell a story about hard work, long hours, and dedication to the museum—and to creating a memorable experience for all of our visitors.
