I do indeed think it was Dr. Kiersten from Fort Dodge sue!

Is this the mystery man behind the Guidestones? Here are three reasons to believe that the man who commissioned the Georgia Guidestones was Herbert H. Kersten, a physician from Fort Dodge, Iowa:

1. Kersten was born on May 7, 1920, and thus would have been 78 on July 14, 1998, the date of the letter in which Robert Christian said he was 78.

2. Kersten lived for many years at the same address seen on one of the envelopes sent to Wyatt Martin.

3. Kersten wrote a lot of letters that were published in newspapers, and in those letters he sounded strikingly similar to Robert Christian.

“Most important of all, America should now begin to direct the attention of the world to solving the fundamental problem which threatens to engulf all humanity in social and economic catastrophe,” Herbert H. Kersten, M.D. wrote in a letter published by the Des Moines Register on January 25, 1981, less than a year after the Guidestones were unveiled. “I refer to the uncontrolled reproduction of our species, which has already caused human numbers to far exceed the level which our planet can support in decency.”

“Rational planning of human reproduction is becoming increasingly essential,” Kersten wrote in a letter the Register published in 1990.

“Contrary to widespread opinion,” Kersten wrote in a 1996 letter to the editor, “our nation is now overpopulated.”

When the filmmakers visited Fort Dodge, the story took a darker turn.

Digging further into the doctor’s background, they interviewed local historian Roger Natte and William Sayles Doan, an art patron and author who said he knew Kersten. Doan, who died in 2015, said Kersten used to brag about his friendship with William Shockley, the Nobel Prize-winning inventor who later became a notorious eugenicist.
