Hawa Abdi"Dr. Hawa Abdi studied medicine in Ukraine before returning home to become one of the first female gynecologists in Somalia. She eventually graduated from law school at Somali National University and opened a one-room clinic that later became the Hawa Abdi hospital and camp. Here, some 100,000 Somalis, many of them refugees in their own country, receive food and medical care—no matter what their clan." Jill Abramson As managing editor of The New York Times, Manhattan native Jill Abramson was a vocal champion for the newspaper's female employees, often throwing parties to celebrate their promotions and quietly encouraging their ambitions. The efforts endeared her to the women on staff, but reportedly alienated her from many of the men. Nonetheless, last fall, she took the helm as the storied paper's first female executive editor. Lynsey AddarioDespite having no formal training in photography, Lynsey Addario is one of today's most respected photojournalists. Addario puts her life in jeopardy while bringing faces and scenes from war-torn spots like Darfur and Afghanistan to the pages of Time, The New York Times, and Newsweek. She has also used her work to bring attention to women's-rights issues in the developing world, documenting life under the Taliban and burn victims in Pakistan—efforts that have earned her honors from the Overseas Press Club. Her job does, of course, have its risks. In the midst of Libya's uprising, Addario was captured and held by the Libyan Army, whose members beat and sexually assaulted her. Gareth CattermoleAdeleThe British-born international soul-singing sensation values equally her roles as musician and inspiration for women. Daughter of a single teenage mother, Adele has released two widely acclaimed albums that are named for the ages she was when making them—19 and 21—and seems to have a lock on the No. 1 slot on the Billboard charts. A major supporter of Sands, a U.K.-based stillborn and neonatal-death charity, Adele requires concertgoers who get free tickets to her performances to donate to the support group. Chimamanda Ngozi AdichieChimamanda Ngozi Adichie is a Nigerian writer whose work has helped inspire new cross-generational communication about the Biafran War. One of The New Yorker's "20 under 40" top fiction writers, she is considered Africa's freshest voice and the heir apparent to Chinua Achebe, who has said of her writing, "We do not usually associate wisdom with beginners, but here is a new writer endowed with the gift of ancient storytellers." Pegah Ahangarani In July 2011 actress Pegah Ahangarani was scheduled to travel to Germany to cover the Women's World Cup for Deutsche Welle TV's Farsi service. But a few days before she was supposed to leave, she was subpoenaed and arrested by Iranian security officials, triggering loud protests from an outraged worldwide audience. After being held at notorious Evin Prison for 17 days, Ahangarani was released on bail. Not one to shy away from danger, the actress had been interrogated by government forces in 2009 after she became a public supporter of Mir Hossein Mousavi during the contested elections. Noorjahan AkbarAt 19 years old, Noorjahan Akbar's impassioned activism seems beyond her years. She has spearheaded efforts in her native Afghanistan ranging from a program called Voices for Hope, which teaches Afghan orphans creative writing, to rallying young people to campaign for Hamid Karzai's challenger in the 2009 presidential election in an effort to change "politics as usual." But Akbar's most recent initiative is her most ambitious. In April 2011, Akbar cofounded Young Women for Change, dedicated to working for gender equality in Afghanistan. Just a few months after launching, YWC staged a march against street harassment in Kabul, a rare form of protest in the country. Peter Macdiarmid / Getty ImagesSue AkersSue Akers is fighting to separate fact from fiction in a scandal embroiling England's top newspapers, politicians, and celebrities. As accusations of privacy breaches and widespread corruption spread through the U.K., Akers, the deputy assistant commissioner of Scotland Yard, took charge of three inquiries to investigate some 2,000 phone-hacking claims, unauthorized access to personal computers, and illegal payments to police. The investigation centers on media mogul Rupert Murdoch and has exposed the unprecedented influence his conglomerate, News Corp., holds across Britain. APZainab al-KhawajaAs Bahrain's most prolific blogger, Zainab al-Khawaja has many reasons to be angry. In December she was arrested at an antigovernment protest, gaining fame as pictures of her being dragged across the ground spread around the Internet. Al-Khawaja's father is Bahrain's most well-known political dissident; along with her husband and three other male relatives, he has been imprisoned since after the start of Bahrain's Arab Spring in February 2011. Her arrest and the imprisonment of her family members haven't deterred the blogger, who swears to continue protesting and tweeting until there is democracy in her country. Tal al-MallohiLast February, Tal al-Mallohi, a high-school student, stood in court chained and blindfolded and was sentenced to five years in prison, accused of being a U.S. spy. She had been detained without charges or legal representation for her blog, on which she wrote notes and poetry about longing for a role in building Syria's future. After her arrest Amnesty International named al-Mallohi, now 21, the youngest prisoner of conscience and called for her release. Despite the ensuing global movement demanding freedom for al-Mallohi, Syrian officials have released few details about her whereabouts or condition. MOHAMED MESSARAIman Al-Obeidi Libyan law student Iman al-Obeidi made international headlines last year when she burst into Tripoli's Rixos Hotel and told the international press corps that Muammar Gaddafi's government troops had beaten and gang-raped her, then attacked the journalists who tried to help her. Described by The Washington Post as a "symbol of defiance" against the Gaddafi regime, al-Obeidi was written off by government representatives as a drunk, a prostitute, a thief, and mentally ill; they claimed she would be charged with slander. After first escaping to Tunisia and later Qatar, al-Obeidi was granted asylum in the United States in June. Joseph Barrak, AFP / Getty Images Nadia Al-SakkafAs editor in chief of the Yemen Times, Nadia al-Sakkaf has challenged the image of Yemeni women and pushed the boundaries of their role in society. Assuming leadership of the independent English-language paper in 2005, al-Sakkaf fought to bring gender equality to the newsroom—often struggling against the entrenched beliefs of her male staff. She considers herself a "bridge," working to help Yemeni women escape the confines of their traditional role in society and reach their potential while also showing "her Yemen" to the world. In the past year al-Sakkaf has committed her paper to covering Yemen's revolution. Ziyah Gafic for Newsweek Manal Al-SharifLast year, Manal al-Sharif was arrested and jailed for nine days—for driving a car. While the act itself isn't technically against the law in her home country of Saudi Arabia, strict religious edicts have effectively meant it's prohibited for women—along with opening bank accounts, getting a passport, or even going to school without a male family member. Al-Sharif, a single mother and information-technology specialist, didn't let her imprisonment dissuade her. She has become the face of the Women2Drive campaign, and in January, she announced that she was suing the traffic police to get a license. Anseth AndrewsFor 27 years, Asenath Andrews has been the principal of the Ferguson Academy for Young Women, a college-prep school in Detroit for pregnant teens. Along with typical academic courses, Ferguson offers such life lessons as parenting, home repair, and nutrition. Andrews transformed her school's surrounding land into an urban farm, complete with chickens, rabbits, and even horses; she uses the farm to teach students how to be self-sufficient and care for living things. The school doubles as a nursery so moms can be near their babies once they're born—and not drop out of school. And to graduate, every student must gain acceptance to college. David Karp / AP PhotoMichelle BacheletAt 60, Michelle Bachelet has lived more lives than most. She was a political prisoner under the brutal Pinochet regime before being forced into exile. Upon her return to Chile, she became a pediatrician, then a minister of health. In 2006 she was elected to be the first female president of Chile. It was a particularly turbulent period: Two years after taking the job, the world financial crisis struck. Two years later, a magnitude-8.8 earthquake ravaged the country. Nevertheless, Bachelet left office with the highest approval rating in Chile's history. She is now the director of U.N. Women, a United Nations initiative focusing on women's equality worldwide. Alex Wong / Getty ImagesMichele BachmannShe is a tax attorney turned state senator turned Republican congresswoman, the first woman in Minnesota's history to be elected to the House of Representatives. And this year Michele Bachmann was a presidential candidate, helming an often controversial campaign until dropping out of the race in January. She is a figure deeply linked to the Tea Party and its cries for smaller government. But in another realm, Bachmann is known as a mother—to almost 30 children: five of them her own, 23 in foster care. Andrew H. Walker / Getty ImagesRoseanne Barr She gave depth, dimension, and sass to the traditional sitcom wife and mother in Roseanne, her saucy nine-season television show. With a memoir out last year and a new show in the works, Roseanne Barr is currently campaigning for the Green Party's nomination for president. Barr has always spoken loudly for justice and her beliefs and has used comedy to break down old stereotypes of women as housekeeping sex objects. AFP / Getty Images Sihem BensedrineTunisian journalist Sihem Bensedrine spent 20 years exposing human-rights violations under the repressive regime of President Zine al-Abidine Ben Ali at great risk to herself and her family. In the late '90s she founded an independent news website and started two organizations: one monitoring Tunisia's human-rights conditions and the other promoting freedom of speech. Despite multiple beatings and a two-month imprisonment in 2001, Bensedrine didn't waver in her devotion to raising awareness. In 2009, with her safety in jeopardy, she fled the country. Bensedrine returned when Ben Ali was overthrown in January 2011 to take the lead of the Arab Working Group for Media Monitoring. Luca BrunoEmma Bonino Since her election to Italy's Chamber of Deputies in 1976, Emma Bonino has had a productive career working for human rights. From 2001 to 2004, Bonino was a visiting professor in Cairo supporting humanitarian issues in the Middle East and North Africa. She has also campaigned tirelessly for the ratification of Africa's Maputo Protocol, which guarantees women's rights to social and political equality and reproductive health, and is helping to put an end to female genital mutilation.
