Solomon R. Guggenheim’s wholehearted embrace of modern art around the age of 68 was not so dissimilar from his philosophy for succeeding in business. He had never shied away from pioneering, or introducing novel methods, in his prosperous career as a mining industrialist. Having collected art privately since the 1890s, he was ripe for fresh inspiration when he fatefully encountered the German‑born artist Hilla Rebay and the innovations of the contemporary avant-garde. Guggenheim and Rebay were closely aligned from 1929, when they began assembling an art collection grounded in nonobjectivity—a strand of abstraction with spiritual underpinnings—until Solomon’s death 20 years later. This defining focus distinguished the eponymous foundation Guggenheim established in New York in June 1937. Two years later the Museum of Non‑Objective Painting, the forerunner of the Solomon R. Guggenheim Museum, debuted in New York.
