It was 1915, and the population of North Dakota was approximately 600,000 people and growing. To attract more immigrants to the state, the State Immigration Department hired Frithjof Holmboe, a Norwegian immigrant, to travel around North Dakota to produce promotional films showcasing the positive characteristics of several counties.  (We have not found any North Dakota winter footage from Holmboe.)  As the state began to fall into an economic depression in 1921, Holmboe closed up the Publicity Film Company studio in Bismarck and moved to California.

It was not until the 1970s that the State Historical Society of North Dakota (SHSND) found the films.  Tucked tightly away in a storage building at Fort Abraham Lincoln, the original 35mm nitrate films had visible signs of deterioration; many were oozing liquid and covered with dust. After the discovery, the SHSND, with the help of the American Revolution Bicentennial Commission, shipped the original 35mm films to a lab in New Jersey to convert the originals into 16mm safety film.  The lab was not able to save all of the film; some of it had almost completely deteriorated. The new 16mm safety film of Frithjof Holmboe’s work arrived back at the State Archives for preservation and was eventually placed in a freezer to halt deterioration.

Recently, we braved the -5°F temperature of the freezer and took the safety film out to re-digitize it in a less compressed format. Before re-digitizing the film, we cleaned it to remove any dust and debris that may compromise the picture quality. Cleaning also helps to preserve it, along with the low temperature and low humidity that is in the freezer.

To clean the film, we use a 91% rubbing alcohol and a lint free cloth. The higher the alcohol content the quicker the liquid dries, allowing us to digitize the film almost immediately after cleaning.

Digitizing Station

The equipment we use to digitize the film into a digital file.

We placed the 16mm Holmboe film onto our Tobin Video Transfer machine. This machine has a built-in video camera that can record sound and video at the same time. Our BlackMagic DeckLink then captures the film. The DeckLink records the footage in an Apple ProRes format. Originally, we digitized the film into mp4 format because it takes up less space and is a popular format; however, in order to use our historic film in the new expansion exhibits, we needed a less compressed format. After we digitized the film, we placed it back into the freezer. Since technology is always changing, there is no doubt we will be revisiting the Holmboe film again to re-digitize it into the next best format.

Although Frithjof Holmboe’s film is our oldest collection, it is only one of many film and video collections preserved at the State Archives. Our film and video collections include family films, commercial films, state agency films, and news films. If you have any questions about our collections or contributing to the collection, please contact Lindsay at
