The Kasiska family’s legacy in Pocatello began with William F. Kasiska, who immigrated from East Prussia (now part of Germany) with his wife, Mary. Their journey took them from New York to Wisconsin, Seattle, and finally to Pocatello in 1890.
William Kasiska was a visionary entrepreneur and civic leader. He invested in land, operated banks and ranches, and served two terms as Mayor of Pocatello. The Kasiskas owned significant real estate throughout the city, including:
- The Bannock Hotel (Simplot Square is now located where the Bannock Hotel once stood)
- The Kasiska Building (once located at the corner of W. Lewis and S. Arthur)
- Their residence at 155 S. Garfield
- The home now occupied by the President of Idaho State University
In the 1970s, both the Kasiska and neighboring Dr. Minnie and William F. Howard's home were relocated near the west end of Chubbuck Road to allow for future expansion of the Public Library, now known as the Marshall Public Library in Historic Downtown Pocatello.
William and Mary left a substantial estate to their daughters, Mabel and Eva, who carried on the family’s enterprises. Mabel Kasiska was one of Idaho’s first female banking executives. She owned and managed a bank in Lava Hot Springs, served on the Board of Directors of the Cassia National Bank in Burley, and invested in the Twin Falls Bank.
The Kasiska family left an enduring mark on Pocatello through their leadership, philanthropy, and community investment.
