Helen Reddy, the Australian singer behind feminist anthem I Am Woman, has died aged 78.
Reddy died on Tuesday in Los Angeles, her family said in a statement on Facebook.
Her children Traci Donat and Jordan Sommers described her as a “wonderful mother, grandmother, and a truly formidable woman”.
“Our hearts are broken. But we take comfort in the knowledge that her voice will live on forever.”
Reddy had a string of pop and rock hits in the 1970s, but is best known for the 1972 anthem I Am Woman – a rousing tune which became prominent in the women’s liberation movement.
It went on to sell over one million copies and became a defining song of second-wave feminism.
