Patricia Dunn, former chairwoman and CEO of Barclays Global Investors and former chairman and director at Hewlett-Packard Co., Palo Alto, Calif., died on Sunday.
She was 58.
The cause of death was not immediately released, but Ms. Dunn had been battling cancer.
Ms. Dunn was chairman and CEO at BGI from 1998 to 2002 following three years as co-chairman and co-CEO. She stepped down from the role in 2002 to take on a part-time role of non-executive vice chairman while undergoing treatment for cancer. She left that role in October 2006.
She became a director at HP in 1998 and was elected chairman of the board in February, 2005 until she left in September 2006.
While at Hewlett-Packard, Ms. Dunn faced felony fraud charges stemming from allegations that the company used false pretenses to access individuals' phone records during the company's investigation of media leaks. Those charges were dropped in March 2007 by Santa Clara County (Calif.) Superior Court Judge Ray Cunningham, in part because of Ms. Dunn's health.
“Pattie Dunn worked tirelessly for the good of HP,” according to a statement released Monday by Hewlett-Packard. “We are saddened by the news of her passing, and our thoughts go out to her family on their loss.”
Bobbie Collins, spokeswoman for BlackRock, which bought BGI in June 2009, could not be immediately reached for comment.
