Happy Birthday Naum Gabo!! Russian born in 1890 and brother of Anton Pevsner, Gabo is credited with inventing Constructivism. Certainly influenced by Cubism and the Futurists, the revolutionary artist was intent on a world where art served society and used materials from the machine age therefore was constructed out of space and time. In defense of Constructivism, he wrote the Realistic Manifesto in 1920 after exhibiting his constructions for the first time. His art inspired many to achieve a new art, lying somewhere between painting and sculpture reluctant to totally abandon “fine” art.
