LOS ANGELES — Richard Landon Kassebaum, a filmmaker who documented his Republican family’s political experiences, which included his grandfather Alf Landon’s 1936 presidential bid, died Wednesday. He was 47.

Kassebaum, a longtime Los Angeles resident, died of cancer at a Knoxville, Tenn., hospital, said his mother, Nancy Kassebaum Baker, the former U.S. senator from Kansas. He was diagnosed 14 months ago with a brain tumor.

As a graduate film student at the University of Southern California, he made “Alf Landon: My Talk With Papa” not long before his grandfather died at 100 in 1987. Landon was governor of Kansas when he lost the presidential election to Franklin Delano Roosevelt in a landslide. Making the film was stressful, Kassebaum later recalled, because his grandfather “wasn’t cooperative.”

In 2002, Kassebaum turned his camera on his brother Bill, a rancher-lawyer who successfully ran for a seat in Kansas’ House of Representatives. During five weeks on the campaign trail, Kassebaum said he was surprised by the gentility of local Kansas politics.

“Bill’s Run: A Political Journey in Rural Kansas” captured “a comical and sometimes painful quest of quixotic proportions (as his brother) fights to preserve a lifestyle quickly disappearing from rural America,” read the review in the Nashville Tennessean when the show aired on PBS in 2004.

Among the programs Kassebaum produced for PBS were “Woodrow Wilson and the Birth of the American Century” (2002) and “John Brown’s Holy War” (2000).
