On March 6, 1936, after picking beets in the
Imperial Valley, Thompson and her family were traveling on
U.S. Highway 101 towards
Watsonville "where they had hoped to find work in the lettuce fields of the
Pajaro Valley." On the road, the car's
timing chain snapped and they coasted to a stop just inside a
pea-pickers' camp on
Nipomo Mesa. They were shocked to find so many people camping there—as many as 2,500 to 3,500. While Jim Hill, her partner, and two of Thompson's sons went into town to get parts to repair the car, Thompson and some of the children set up a temporary camp. As she waited, photographer Dorothea Lange, working for the
Resettlement Administration, drove up and started taking photos of Thompson and her family. She took seven images in the course of ten minutes. Lange's field notes for the Resettlement Administration were typically very thorough, but on this particular day she had been rushing to get home after a month on assignment, and the notes she submitted with this batch of negatives do not refer to any of the seven photographs she took of Thompson and her family. It seems that the published newspaper reports about this camp were later distilled into captions for the series, which explains inaccuracies on the file cards in the Library of Congress. For example, one of the file cards reads: Twenty-three years later, Lange wrote of the encounter with Thompson: Within days, the pea-picker camp received of food from the federal government. Thompson was quoted as saying: "I wish she [Lange] hadn't taken my picture. I can't get a penny out of it. She didn't ask my name. She said she wouldn't sell the pictures. She said she'd send me a copy. She never did." While the image was being prepared for exhibit in 1938, the negative of the photo was retouched to remove Florence's thumb from the lower-right corner of the image.
Circulation In the late 1960s, Bill Hendrie found unretouched
prints by Lange of
Migrant Mother and 31 other images from the same series in a dumpster at the
San Jose Chamber of Commerce. After the death of Hendrie and his wife, their daughter, Marian Tankersley, rediscovered the photos while emptying her parents' San Jose home. The stamp printing was unusual: daughters Katherine McIntosh (on the left in the stamp) and Norma Rydlewski (in Thompson's arms in the stamp) were alive at the time of the printing; usually, the Postal Service does not print stamps of individuals who have not been dead for at least 10 years. In the same month the U.S. stamp was issued, a print of the photograph with Lange's handwritten notes and signature sold in 1998 for $244,500 at Sotheby's New York. In November 2002, Dorothea Lange's personal print of
Migrant Mother sold at
Christie's New York for $141,500. ==Later life, death, and aftermath==
