Margrit Kennedy (November 21, 1939, Chemnitz - December 28, 2013, Steyerberg) was a German architect, professor, environmentalist, author and world authority on and advocate of complementary currencies and an interest- and inflation-free economy. In 2011, she initiated the movement Occupy Money.
She stated that her work on ecological architecture in 1982 led her to the discovery that it is "virtually impossible to carry out sound ecological concepts on the scale required today, without fundamentally altering the present money system or creating new complementary currencies".
Her most famous book—Interest and Inflation Free Money, Creating an Exchange Medium that Works for Everybody and Protects the Earth (1987)—has been revised several times and translated into 22 languages.
