It is Labor Day here in the U.S. - time to celebrate hard work by hopefully taking a day off from work. A lot of people worked very hard building the 200-inch telescope including these people from the Westinghouse Electric and Manufacturing Company's South Philadelphia plant.
Westinghouse assembled this cast photo of the crew that built the telescope. In this shot they are assembled in the still ring that would later attach the 200-inch mirror to the telescope. We are thankful for the hard work put in by all of the people who helped make the observatory a reality.
Happy Labor Day!
