Melbourne, Australia --Ed Tweddell, the chairman of Ansell Ltd., died Aug. 4 at the age of 64.
His family said in a statement he had been suffering from poor health. Cause of death was not verified and his family said circumstances surrounding his death were unclear.
Tweddell, a former director of National Australian Bank Ltd., had chaired the board of Ansell since November 2001.
He graduated from the University of Queensland with science and medicine degrees and went into private practice before joining Pfizer University, a pharmaceutical giant, where he spent 10 years. In 1986 he was named president and CEO of a consumer and health care firm in Japan and in 1988 he became managing director of a pharmaceutical firm. In 1989, he was appointed to the board of FH Faulding & Co. Ltd., where he served as group managing director and CEO from 1993 to 2001.
He founded Nepenthe Group Pty. Ltd., a major winery in Australia, with his family in 1994 but in recent years stepped away from management of the company, which continued to grow under his son, James, and its management team, the Tweddell family said in a prepared statement.
Tweddell was named to National Australian Bank's board in 1998 but resigned in 2004 as part of a plan to settle a boardroom dispute, according to published reports.
He is survived by his wife Sue, a son and a daughter.
