We watched an excellent documentary on an excellent documentary photographer, Dorothea Lange. I have found out that one can watch the entire episode online, in case you did not get a chance to watch or record it on WGBH on August 29, 2014. The embedded copy below is from the American Masters site.
She was a physically limping but professionally constantly running giant. It is scheduled to show on September 1, 2014, at 3:00 PM on WGBX 44. Set your DVR!
Then visit the photo gallery, See What Dorothea Lange Saw for still photographs.
The video below is not viewable because I do not have a “WGBH Passport” membership. You may be able to find it on your local are PBS, search for “Dorothea Lange Grab a Hunk of Lightning.”
