Problem: Maurice Robert "Mike" Gravel (; born May 13, 1930) is an American politician who was a Democratic United States Senator from Alaska from 1969 to 1981 and a candidate in the 2008 U.S. presidential election. Born and raised in Springfield, Massachusetts, by French-Canadian immigrant parents, Gravel served in the U.S. Army in West Germany, and he later graduated from the Columbia University School of General Studies. He moved to Alaska in the late 1950s, becoming a real estate developer and entering politics. He served in the Alaska House of Representatives from 1963 to 1966 and also became Speaker of the Alaska House.

In the late 1960s and early 1970s the U.S. Department of Defense was in the process of performing tests for the nuclear warhead for the Spartan anti-ballistic missile. Two tests, the "Milrow" and "Cannikin" tests, were planned, involving the detonation of nuclear bombs under Amchitka Island in Alaska. The Milrow test would be a one megaton calibration exercise for the second, and larger five megaton, Cannikin test, which would measure the effectiveness of the warhead. Gravel opposed the tests in Congress. Before the Milrow test took place in October 1969, he wrote that there were significant risks of earthquakes and other adverse consequences, and called for an independent national commission on nuclear and seismic safety to be created; he then made a personal appeal to President Nixon to stop the test.  After Milrow was conducted, there was continued pressure on the part of environmental groups against going forward with the larger Cannikin test, while the Federation of American Scientists claimed that the warhead being tested was already obsolete. In May 1971, Gravel sent a letter to U.S. Atomic Energy Commission hearings held in Anchorage, in which he said the risk of the test was not worth taking. Eventually a group not involving Gravel took the case to the U.S. Supreme Court, which declined to issue an injunction against it, and the Cannikin test took place as scheduled in November 1971. Gravel had failed to stop the tests (notwithstanding his later claims during his 2008 presidential campaign).  Nuclear power was considered an environmentally clean alternative for the commercial generation of electricity and was part of a popular national policy for the peaceful use of atomic energy in the 1950s and 1960s. Gravel publicly opposed this policy; besides the dangers of nuclear testing, he was a vocal critic of the Atomic Energy Commission, which oversaw American nuclear efforts, and of the powerful United States Congress Joint Committee on Atomic Energy, which had a stranglehold on nuclear policy and which Gravel tried to circumvent. In 1971, Gravel sponsored a bill to impose a moratorium on nuclear power plant construction and to make power utilities liable for any nuclear accidents; in 1975, he was still proposing similar moratoriums. By 1974, Gravel was allied with Ralph Nader's organization in opposing nuclear power.  Six months before U.S. Secretary of State Henry Kissinger's secret mission to the People's Republic of China (P.R.C.) in July 1971, Gravel introduced legislation to recognize and normalize relations with China, including a proposal for unity talks between the P.R.C. and the Republic of China (Taiwan) regarding the Chinese seat on the U.N. Security Council. Gravel reiterated his position in favor of recognition, with four other senators in agreement, during Senate hearings in June 1971.

Did he do anything else notable during the Cold War era?

Answer with quotes: By 1974, Gravel was allied with Ralph Nader's organization in opposing nuclear power.

Question:
Scarlett Ingrid Johansson was born in the Manhattan borough of New York City, New York. Her father, Karsten Olaf Johansson, is an architect originally from Copenhagen, Denmark, and her paternal grandfather, Ejner Johansson, was an art historian, screenwriter and film director, whose own father was Swedish. Johansson's mother, Melanie Sloan, a producer, comes from an Ashkenazi Jewish family of Polish and Belarusian descent. She has an older sister, Vanessa, also an actress; an older brother, Adrian; and a twin brother, Hunter.
Johansson's first leading role was as Amanda, the younger sister of a pregnant teenager who runs away from her foster home in Manny & Lo (1996) alongside Aleksa Palladino and her brother, Hunter. Her performance received positive reviews: one written for the San Francisco Chronicle noted, "[the film] grows on you, largely because of the charm of ... Scarlett Johansson," while critic Mick LaSalle, writing for the same paper, commented on her "peaceful aura", and believed, "If she can get through puberty with that aura undisturbed, she could become an important actress." Johansson earned a nomination for the Independent Spirit Award for Best Lead Female for the role.  After appearing in minor roles in Fall and Home Alone 3 (both 1997), Johansson attracted wider attention for her performance in the film The Horse Whisperer (1998), directed by Robert Redford. The drama film, based on the 1995 novel of the same name by Nicholas Evans, tells the story of a talented trainer with a gift for understanding horses, who is hired to help an injured teenager played by Johansson. The actress received an "introducing" credit on this film, although it was her seventh role. On Johansson's maturity, Redford described her as "13 going on 30". Todd McCarthy of Variety commented that Johansson "convincingly conveys the awkwardness of her age and the inner pain of a carefree girl suddenly laid low by horrible happenstance". For the film, she was nominated for the Chicago Film Critics Association Award for Most Promising Actress. She believed that the film changed many things in her life, realizing that acting is the ability to manipulate one's emotions. On finding good roles as a teenager, Johansson said it was hard for her as adults wrote the scripts and they "portray kids like mall rats and not seriously ... Kids and teenagers just aren't being portrayed with any real depth".  Johansson later appeared in My Brother the Pig (1999) and in the neo-noir, Coen brothers film The Man Who Wasn't There (2001). Her breakthrough came playing a cynical outcast in Terry Zwigoff's black comedy Ghost World (2001), an adaptation of Daniel Clowes' graphic novel of same name. Johansson auditioned for the film via a tape from New York, and Zwigoff believed her to be "a unique, eccentric person, and right for that part". The film premiered at the 2001 Seattle International Film Festival; it was a box office failure, but has since developed a cult status. Johansson was credited with "sensitivity and talent [that] belie her age" by an Austin Chronicle critic, and won a Toronto Film Critics Association Award for Best Supporting Actress for her performance.  With David Arquette, Johansson appeared in the horror comedy Eight Legged Freaks (2002), about a collection of spiders that are exposed to toxic waste, causing them to grow to gigantic proportions and begin killing and harvesting. After graduating from PCS that year, she applied to New York University's Tisch School of the Arts; she decided to focus on her film career when she was rejected.
