Airgas, Inc. has announced that its Board of Directors has elected Ellen C. Wolf, senior vice president and chief financial officer of American Water, to fill the vacancy created by the unfortunate passing of William O. Albertini in June 2008.

Wolf has also been appointed to serve as a member of the Audit Committee, replacing W. Thacher Brown, who had been appointed to the Audit Committee in the wake of Albertini’s passing.

Wolf’s term begins immediately and will expire at the 2009 Annual Meeting.

“We are very pleased to welcome Ellen Wolf to the Board of Directors,” said Airgas Chairman and CEO Peter McCausland.

“Her experience as a public company chief financial officer will complement the expertise of our other Board members. We look forward to her contributions to the Board and to the Audit Committee.”

Wolf originally joined American Water, the largest investor-owned US water and wastewater utility company in May 1999, as vice president and chief financial officer. Prior to her return to American Water in March 2006 as the company’s senior vice president and chief financial officer, Wolf served from 2003 to 2006 as senior vice president and chief financial officer for USEC, Inc. and as vice president-treasurer for Bell Atlantic Corporation from 1995 to 1999.
