herself engaged in extra-marital affairs, seemed to tolerate Dalí's dalliances with younger muses, secure in her own position as his primary relationship. Dalí continued to paint her as they both aged, producing sympathetic and adoring images of her. The "tense, complex and ambiguous relationship" lasting over 50 years would later become the subject of an opera, Jo, Dalí (I, Dalí) by Catalan composer Xavier Benguerel. Dalí's first visit to the United States in November 1934 attracted widespread press coverage. His second New York exhibition was held at the Julien Levy Gallery in November–December 1934 and was again a commercial and critical success. Dalí delivered three lectures on Surrealism at the Museum of Modern Art (MoMA) and other venues during which he told his audience for the first time that "[t]he only difference between me and a madman is that I am not mad." The heiress Caresse Crosby, the inventor of the brassiere, organized a farewell fancy dress ball for Dalí on 18 January 1935. Dalí wore a glass case on his chest containing a brassiere and Gala dressed as a woman giving birth through her head. A Paris newspaper later claimed that the Dalís had dressed as the Lindbergh baby and his kidnapper, a claim which Dalí denied. While the majority of the Surrealist group had become increasingly associated with leftist politics, Dalí maintained an ambiguous position on the subject of the proper relationship between politics and art. Leading Surrealist André Breton accused Dalí of defending the "new" and "irrational" in "the Hitler phenomenon", but Dalí quickly rejected this claim, saying, "I am Hitlerian neither in fact nor intention". Dalí insisted that Surrealism could exist in an apolitical context and refused to explicitly denounce fascism. Later in 1934, Dalí was subjected to a "trial", in which he narrowly avoided being expelled from the Surrealist group. To this, Dalí retorted, "The difference between the Surrealists and me is that I am a Surrealist." In 1936, Dalí took part in the London International Surrealist Exhibition. His lecture, titled , was delivered while wearing a deep-sea diving suit and helmet. He had arrived carrying a billiard cue and leading a pair of Russian wolfhounds and had to have the helmet unscrewed as he gasped for breath. He commented that "I just wanted to show that I was 'plunging deeply into the human mind." Dalí's first solo London exhibition was held at the Alex,
