This Sunday, the first installment of Ken Burns’ documentary “The U.S. and the Holocaust,” is set to air on Nine PBS locally from 7 to 9 p.m. The three-part, six-hour series focuses on “America’s response to one of the greatest humanitarian crises of the 20^th century,” according to the PBS website. The second and third parts were supposed to air Monday, Sept. 19 and Tuesday, Sept. 20 at the same time, but a programming change has just been announced.

“To pay homage to Queen Elizabeth’s role on the world stage and to recognize the special relationship that has existed between our two countries, PBS will be carrying the BBC broadcast of Queen Elizabeth’s funeral the morning of Monday, September 19,” PBS said in a statement. “That evening, PBS will also share a recap of the funeral events in a new special from the BBC.”

To accommodate this primetime addition to their schedule, the air dates for “The U.S. and the Holocaust” have been adjusted. The premiere date for the series remains the same, on Sunday, Sept. 18, but episode two will now premiere on Tuesday, Sept. 20, followed by episode three on Wednesday, Sept. 21.

“The U.S. and the Holocaust”

Viewers will listen to firsthand testimony of witnesses and survivors who as children endured persecution, violence and flight from Nazi-controlled Europe during the Holocaust. According to advanced press material, this series delves deeply into the tragic human consequences of public indifference, bureaucratic red tape and restrictive quota laws in America.

Burns, along with co-filmmakers Lynn Novick and Sarah Botstein, are said to have made a documentary that points the camera squarely at America at the time, questioning whether our nation failed to live up to the ideals it was founded on.
