Thomas Edison's Menlo Park Laboratory, Menlo Park, New Jersey, circa 1912
- Thomas Edison's Menlo Park Laboratory "Glass House," Menlo Park, New Jersey - Originally built as a photographic studio and drafting room, the glassblowing shop was fundamental to Edison's enterprise. Edison's incandescent lighting experiments ensured that the laboratory had a voracious appetite for glass -- not only for bulbs but also for associated apparatus such as vacuum pumps. Ludwig Boehm, the laboratory's first master glassblower, worked here -- and lodged in the attic space.
