Grant, Peter. 2020. “A 1918 Influenza Outbreak at Haskell Institute: An Early Narrative of the Great Pandemic.” Kansas History 43 (2): 56–82.
While Haskell was still a boarding school, it was hit with the 1918 influenza outbreak and was part of one of the first waves of a global pandemic. Due to the poor living conditions at the school, students had adverse health outcomes and a much higher mortality rate than other groups that were subject to the same illness. This event is an incredibly important part of Haskell’s history, making this article a highly recommended read.
Warren, Kim. 2007. “All Indian Trails Lead to Lawrence, October 27 to 30, 1926.” Kansas History 30 (1): 2–19.
One of the most important parts of Haskell’s early history was its first Homecoming celebration in 1926 to commemorate their new football field. Against the trend of assimilation, traditional indigenous dances were performed, demonstrating the perseverance of Native American culture. Although there are other articles that discuss this event, this article is recommended for its currency and does not rely on derogatory terms found in older articles.
