JF Ptak Science Books Quick Post
This slightly altered detail is from the central perspective of a photo of workers completing the base for a 10 million cubic foot gas tank1 in Chicago, and appeared in the Scientific American on 23 January 1920. It is a great photo of the beginnings of a considerable project, and the full image (below) stands on its own as a visual accommodation of a segmented space soon to be occupied by something enormous. That said, the guy in the middle of it all caught my attention in all of this. Was he a standard laborer out of position amidst the 200-odd other people there as the shot was being made, wondering where it was he was supposed to be? Or was that a foreman, or somebody else with the freedom to walk around as the great mass fell into position to take care of the job at hand?
Notes
1. It was a big tank: 10,000,000 cu ft is about 75,000,000 gallons, weighing in at about half-a-billion pounds, which is a lot. By spacing out the guys on the perimeter of the base I make it that the circumference of the structure was about 400′.
