Dr. Wolff, the man at the right, is operating an oil bath maintained at a particular temperature while observing a temperature gauge graduated to tenths of a degree in order to measure the temperature response of several Weston cells, used to calibrate voltmeters at the time. His colleague may be crafting the mercurial thermometers used in the experiment,and undoubtedly resting his eyes for the next batch of measurements he was to take following Dr. Wolff. Apparently Dr. Wolff was one of the first to make use of least squares fitting to produce a calibration curve, a result of this experiment.
