A. Andersen founded the accounting firm Arthur Andersen & Co. in 1913 in Chicago. He headed the firm until his death in 1947. The firm grew rapidly but eventually failed to withstand pressure to prioritize revenue over ethics. It provided accounting services for Enron but failed to follow accounting standards and destroyed documents, contributing to Enron's collapse in 2001. In response, Congress passed reforms like the Sarbanes-Oxley Act to strengthen oversight of public accounting. Arthur Andersen was forced into bankruptcy as a result of its role in the Enron scandal.
