This post is part of a series on some of the most memorable companies that have disappeared.

Arthur Andersen (1913 to 2002) spent decades as a leading accounting and consulting firm. Founded in 1913, it was once a member of the "Big 8" accounting firms, which later became the "Big 5." Andersen was the accountant for MCI and Worldcom. Even though it's been dead for six years, it left one offspring -- it spun off its Andersen Consulting unit in 1989. The renamed Accenture (NYSE: ACN) went public at $14.50 in July 2001 -- the share price is up 176% since then.

Andersen's downfall was its role as Enron's auditor. It used its credibility to bless Enron's special purpose entities and a whole host of illegal accounting. In 2002, the firm voluntarily surrendered its licenses to practice as CPAs after being found guilty of criminal charges, resulting in the loss of 85,000 jobs.

The lesson is to resist the lure of big money to pull you away from your values. Enron's pile of cash was irresistible to Andersen's leaders. And their lack of moral fiber cost a storied and proud firm its existence.
