Scope and content
On February 28, 1957, a series of photographs were taken apparently at an unidentified testing laboratory. Several technicians were pictured running tests on various machines. This man is intently gazing at the meter, which is registering all zeros, and has a notepad with calculations close at hand. The machine was manufactured by the Tinius Olsen Testing Machine Co. of Philadelphia. Part of the machine is labeled "Massachusetts Institute of Technology Folding Endurance Testing". Working in conjunction with the Tinius machine is a speed reducer from Janette Mfg. Co. of Chicago. Photograph ordered by Merchandising Factors, Seattle.
