Anne M. Mulcahy, 2007

A Xerox veteran who began her career at the vendor in the mid-1970s, Mulcahy was appointed COO and, one year later, CEO at a time when the company found itself facing a U.S. Securities and Exchange Commission investigation tied to accounting abnormalities and sitting on $18 million in debt. Mulcahy, now held accountable for the mess as Xerox's embattled leader, courageously cooperated with investigators, offered testimony and eventually announced a $2 billion revenue restatement. Over her next eight years as CEO and chairwoman, Mulcahy got Xerox back on its feet, earning CEO of the Year 2008 in Chief Executive magazine and many other honors along the way.
