Arthur Andersen was a prominent accounting firm founded in 1913 by Arthur E. Andersen and his partner, Clarence DeLany. It became one of the "Big Five" accounting firms, providing auditing, tax, and consulting services to a wide range of clients, including large corporations. However, the firm faced a major scandal in the early 2000s due to its involvement in the collapse of Enron, an energy company. This led to a loss of credibility and legal issues, ultimately resulting in the firm's dissolution in 2002. The scandal highlighted the importance of ethical practices in accounting and auditing.
