Photograph of four Lear Corporation Research and Development Division workers at work, September 1950. Four men gather around a table, and appear to examine a single device. The man in the middle sits, and holds the device in his left hand, while the other three bend slightly to look at it. The man at right points a pencil, gesturing towards the machine bit. On the desk, what appears to be a day calendar sits beside a pen holder and other papers.; Photoprint indentifies the men in the photo from lef to right as: David J. Green; Charles J. Breitwieser, Kenneth M. Miller, and H. Nils Eklund.
