Bank One

Bank One Corporation was a major American financial services company that operated as one of the largest banking institutions in the United States prior to its acquisition. While primarily a commercial and retail bank, it maintained a significant healthcare lending and investment division that provided capital to various life science and healthcare organizations. The company was headquartered in Chicago, Illinois, and played a pivotal role in financing healthcare infrastructure and corporate expansions during the late 20th century. In 2004, Bank One merged with JPMorgan Chase & Co., effectively ending its independent operations and integrating its assets into the larger global financial entity.
