At 82, Gabo is the leading 'constructivist' sculptor alive today. Born in Russia in 1890 and now living in America, he was the originator of the famous 'Realistic Manifesto,' a key document in the history of modern art and as true today as when it was written in 1922. In this film Gabo speaks as an eye-witness of the birth of modern art in Germany where he studied, and in his native Russia during the years of the Revolution. He also explains, in words and images of great clarity and power, the philosophy of his own work, from the 80-ft-high sculpture in the heart of Rotterdam to his more recent project, a fountain for a site in London.
