A graduate of the New York Trade School's Electrical program in 1958, Dennis Mahoney is show at work for the Consolidated Edison Company in New York. Caption written on reverse reads "Dennis J. Mahoney is shown closing the Armature Switch of a Rotary Converter in a D.C. substation. The average rotary in our stations has a capacity of 4,200 K.W. and there are 30 such stations in Manhattan with an annual output of 800,000 amperes. Although the D.C. load is gradually being reduced, it can be seen that there is still considerable demand for direct current in Manhattan." Black and white photograph.
