Robert Gessner was a Jewish American writer, teacher, poet, and novelist who replaced Thomas Wolfe as an English professor at NYU in 1930. Several years later, in 1934, Warner Brothers made his book "Massacre" into a film.
In the same year that the film was made, Gessner "traveled to Europe and the Middle East, where he filmed at least 10 reels documenting Jewish life."
The film was recently donated to the United States Holocaust Memorial Museum, and a significant amount of it was damaged.
In this video the archivist in charge of the collection, Lindsay Zarwell, explains the importance of its history, and describes the methods they used to restore and preserve it.
