As the scale of Edison's investigations grew so did the complex, but this building -- dedicated to experimental activities -- was always understood to be the heart of the enterprise.

- Notebook from the Laboratory of T.A. Edison Menlo Park, New Jersey, 1929 - To celebrate the 50th anniversary of the incandescent electric lamp, Henry Ford hosted the Light's Golden Jubilee event in Dearborn, Michigan. During the festivities, Thomas Edison and former assistant Francis Jehl re-enacted the 1879 test of Edison's first successful light bulb in Greenfield Village's detailed reproduction of his Menlo Park Laboratory. Jehl provided the elderly inventor with handwritten notes to help guide Edison through the re-enactment.

- Menlo Park Laboratory Glass House, Menlo Park, New Jersey, 1878-1886 - 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.

- Menlo Park Machine Shop - The presence of a machine shop (and of foreman / head machinist John Kruesi) was fundamental to the success of Menlo Park. This well-equipped facility -- built to replace the small machine shop originally installed in the laboratory -- enabled Edison and his associates to not only rapidly prototype iterations of experimental devices but also facilitate their eventual, profitable manufacture.
