Mysteries solved!

Several people recognized Perry Justice in this photo taken in the Financial and Statistical Accounting Department in the Power Building in Charlotte. The photo was used in the 1972 annual report. Mary Hoy and Laura Mullinax put us in touch with Billy Haywood, who wrote: "I remember the photographer posing him for the picture. Perry's pencil was normally in his right hand and his calculator was normally angled more to the right. I happened to work at the desk directly behind Perry. I posed myself trying to appear hard at work! I recognize some of the other people in the background: Karen Jarvis Zapata with the updo, Ron Barbee beside her, Dave Davis at the desk on the right and the backside of Paul Davis on the right. Don Stratton always said he was the guy in the very back with his backside out." 

Adam Williams tracked down information about this 1953 photo from Public Service of Indiana. He checked with Richard “PR” Robb, a retired PSI/PSI Energy/Cinergy/Duke Energy employee who "still works for our project teams at Gibson Station. PR says the person standing in front of the control panel is substation operator John Detrick taking readings from the Bank No. 6 meters at the New Castle I avenue substation."
