This week we have two images for our Palomar Observatory History Photo of the Week.
The top photo shows a group of people with Edwin Hubble (at right) greeting the 200-inch Pyrex disc as it arrived at Lamanda Park in Pasadena, CA on April 10, 1936.
The photo below, also taken by Ferdnand Ellerman, shows the scene later that day as a crowd gathered to see the 200-inch as it was removed from the rail car.
The next day it was taken by the Belyea Truck Co. to the optical shop at Caltech. Work on the 20-ton glass disc began shortly there after. No one at the time would have imagined that it would remain there for eleven and a half years.
