Gertrude Rand Ferree has been awarded the Gold Medal of the Illuminating Engineering Society. Dr. Rand, together with her late husband, Dr. Clarence E. Ferree, established much of the basic information about the eye and its response to light. They studied speed of vision, improvement of visual activity, and contrast sensitivity of normal and abnormal eyes. Their names have appeared on some 50 technical papers as well as on a number of patents for lighting devices and optical and ophthalmological instruments, including the Ferree‐Rand perimeter, the light sense tester, and the central vision scotometer.
