Fritjof Capra (born February 1, 1939) is an Austrian-born American author, physicist, systems theorist and deep ecologist.

While at Berkeley, he was a member of the Fundamental Fysiks Group, founded in May 1975 by Elizabeth Rauscher and George Weissmann, which met weekly to discuss philosophy and quantum physics.

Capra contributed to the screenplay for the 1990 movie Mindwalk, starring Liv Ullmann, Sam Waterston and John Heard.

Capra advocates that Western culture abandon conventional linear thought and the mechanistic views of Descartes.

He is a founding director of the Center for Ecoliteracy located in Berkeley, California, which promotes ecology and systems thinking in primary and secondary education.
