Repost from @si_invention. We're looking forward to seeing this on display here when our first floor of our West Wing opens this summer. #WizardOfOz ・・・
The Lemelson Center is looking forward to July…and not just because we’re all sick of the cold! Places of Invention opens at @国立アメリカ歴史博物館 July 1 after over a decade of research, documentation, writing, and design. As we get ready to install the exhibition, two of the large objects have come to the Museum from our off-site storage. Today we uncrated them; next our conservators will evaluate and treat any issues.
Left, a Lincoln Milling Machine, 1861, will be on display in the Hartford, CT case study. Tool builder George S. Lincoln of Hartford’s Phoenix Iron Works manufactured this type of general-purpose milling machine. It was used in nearly every Hartford factory. Its high-speed rotary cutting blade shaved excess material from a metal workpiece.
Right, Technicolor Motion Picture Camera, 1937, is part of our Hollywood case study. This camera, used on the set of The Wizard of Oz, is based on the patent received by Joseph A. Ball and Gerald F. Rackett in 1937. The box enclosing the camera, called a “blimp,” muffled the noisy camera during filming.
