Typed note attached to negative states "ground-breaking ceremonies at the California Institute of Technology yesterday for the $1,000,000 group of dormitories were featured by the use of a steam shovel, instead of the usual small spade, while an added appropriate touch was given by the punch, a synthetic concoction. Charles Dickerman is seen at controls of shovel. Sidney Zipser poises the bottle of punch (just before he dropped it) and Roscoe Downs poses in left foreground."

This photograph appears with Los Angeles Times article, December 8, 1929, Touch Controls Niagara of Power, New Leash Curbs Voltage, Switch Devised at Caltech Tames Thunderbolts; Millikan and Sorensen Back Development. Scientist Demonstrates Novel Mechanism: Prof. R.W. Sorensen presses button which releases 1,000,000 volts into the new Millikan-Sorensen vacuum switch. … Its purpose is to shunt Niagaras of power from one track to another. … “Heretofore high-voltage currents have been controlled by means of switches immersed in oil … In our switch we substitute a vacuum for the oil.” …
