Wheatley–Mapother low-temp lab, 1957  From the Illinois Alumni News, Vol. 36, No. 3 (April 1957). 'This apparatus on the first floor of the Physics Laboratory looks complex. It doesn't seem so to these physicists: at right, Prof. Dillon E. Mapother; seated with notebook, Prof. J.C. Wheatley; standing in the center of the picture, Thomas Estle, and at back and left, Howard Hart. Estle is an Eastman Kodak fellow and Hart a National Science Foundation fellow. The apparatus includes a cryostat in which temperatures within a few thousandths of one degree of absolute zero (about 459 below zero Fahrenheit) are produced by a process know as adiabatic demagnetization. At low temperatures, materials take on very unusual properties, the study of which often gives special insight into the internal structure, forces and processes in nature.'
