In 1921, Ève set off on her first journey across the Atlantic Ocean: that spring, she sailed with her sister and mother on board the ship
RMS Olympic to New York City. Marie Curie, as a two-time laureate of the Nobel Prize, the discoverer of
radium and
polonium, was welcomed there with all due ceremony; her daughters were also very popular with American high society. Radiant at parties and joyous, Ève was dubbed by the press "the girl with radium eyes". During the trip Ève and Irène also acted as their mother's "bodyguards" – Marie, usually focused on research work and preferring a simple life, did not always feel comfortable facing the homage paid to her. While in the United States, Marie, Irène and Ève met President
Warren G. Harding in Washington, D.C., saw
Niagara Falls and went by train to see the
Grand Canyon. They returned to Paris in June 1921. Ève, like her sister Irène, graduated from the
Collège Sévigné, a non denominational private high school in Paris, where she obtained her baccalaureate in 1925. Meanwhile, she also improved her piano skills and gave her first concert in Paris in 1925. Later, she performed on stage many times, giving concerts in the French capital, in the provinces and in
Belgium. After Irène married Frédéric Joliot in 1926, Ève stayed with her mother in Paris, taking care of her and accompanying her on trips throughout France,
Italy, Belgium, and
Switzerland. In 1932, they also accompanied the President of
Czechoslovakia,
Tomáš Masaryk, on his trip to Spain. Although she loved her mother, Ève had a quite different personality from her (and from her sister Irène). She was not interested in science, preferring the
humanities. Unlike her mother, she was always attracted by refined life. Whereas Marie usually wore simple, black dresses, Ève always cared about smart clothes, wore high-heeled shoes and make-up, and loved shining at parties. However, both Ève and Irène nursed their mother with devotion until her death. Marie, ill with
aplastic anemia, probably caused by her long-term exposure to ionizing radiation, died on July 4, 1934. ==After mother's death==
