Brâncuși's impact, with his vocabulary of reduction and abstraction, is seen
throughout the 1930s and 1940s, and exemplified by artists such as Gaston Lachaise, Sir Jacob Epstein, Henry Moore, Alberto Giacometti, Joan Miró, Julio González, Pablo Serrano, Jacques Lipchitz [123] and by the 1940s abstract sculpture was impacted and expanded by Alexander Calder, Len Lye, Jean Tinguely, and Frederick Kiesler who were pioneers of
Kinetic art.
In earlier decades, as will undoubtably be the case now, a great deal was written about Soto (1923 > 2005), and,
throughout his lifetime he was passionately vociferous in extolling and defending the virtues of
kinetic art in numerous and insightful press interviews and letters.
