Problem: George Michael Cohan (July 3, 1878 - November 5, 1942), known professionally as George M. Cohan, was an American entertainer, playwright, composer, lyricist, actor, singer, dancer and producer. Cohan began his career as a child, performing with his parents and sister in a vaudeville act known as "The Four Cohans." Beginning with Little Johnny Jones in 1904, he wrote, composed, produced, and appeared in more than three dozen Broadway musicals. Cohan published more than 300 songs during his lifetime, including the standards "Over There", "Give My Regards to Broadway", "The Yankee Doodle Boy" and "You're a Grand Old Flag".

From 1899 to 1907, Cohan was married to Ethel Levey (1881-1955; born Grace Ethelia Fowler), a musical comedy actress and dancer. Levey and Cohan had a daughter, actress Georgette Cohan Souther Rowse (1900-1988). Levey joined the Four Cohans when Josie married, and she starred in Little Johnny Jones and other Cohan works. In 1907, Levey divorced Cohan on grounds of adultery.  In 1908, Cohan married Agnes Mary Nolan (1883-1972), who had been a dancer in his early shows; they remained married until his death. They had two daughters and a son. The eldest was Mary Cohan Ronkin, a cabaret singer in the 1930s, who composed incidental music for her father's play The Tavern. In 1968, Mary supervised musical and lyric revisions for the musical George M!. Their second daughter was Helen Cohan Carola, a film actress, who performed on Broadway with her father in Friendship in 1931. Their youngest child was George Michael Cohan, Jr. (1914-2000), who graduated from Georgetown University and served in the entertainment corps during World War II. In the 1950s, George Jr. reinterpreted his father's songs on recordings, in a nightclub act, and in television appearances on the Ed Sullivan and Milton Berle shows. George Jr.'s only child, Michaela Marie Cohan (1943-1999), was the last descendant named Cohan. She graduated with a theater degree from Marywood College, Scranton, Pennsylvania, in 1965. From 1966 to 1968, she served in a civilian Special Services unit in Vietnam and Korea. In 1996, she stood in for her ailing father at the ceremony marking her grandfather's induction into the Musical Theatre Hall of Fame at New York University.  Cohan was a devoted baseball fan, regularly attending games of the former New York Giants.  He died of cancer at the age of 64 on November 5, 1942, at his Manhattan apartment on Fifth Avenue, surrounded by family and friends. He received his last rites from Mgr. John J. Casey, representing Archbishop Francis Spellman, and Rev. Francis X. Shea, vicar of the Archdiocese of New York. His funeral was held at St. Patrick's Cathedral, New York and was attended by thousands of people, including five governors of New York, two mayors of New York City and the Postmaster General. The honorary pallbearers included Irving Berlin, Eddie Cantor, Frank Crowninshield, Sol Bloom, Brooks Atkinson, Rube Goldberg, Walter Huston, George Jessel, Connie Mack, Joseph McCarthy, Eugene O'Neill, Sigmund Romberg, Lee Shubert and Fred Waring. Cohan was interred at Woodlawn Cemetery in The Bronx, New York City, in a private family mausoleum he had erected a quarter century earlier for his sister and parents.

Question:
Ai Weiwei (Chinese: Ai Wei Wei ; pinyin: Ai Weiwei,  English pronunciation ; born 28 August 1957 in Beijing) is a Chinese contemporary artist and activist. His father's (Ai Qing) original surname was written Jiang (Jiang ). Ai collaborated with Swiss architects Herzog & de Meuron as the artistic consultant on the Beijing National Stadium for the 2008 Olympics.
On 22 June 2011, the Chinese authorities released Ai from jail after almost three months' detention on charges of tax evasion. Beijing Fa Ke Cultural Development Ltd. (Chinese: Bei Jing Fa Ke Wen Hua Gong Si ), a company Ai controlled, had allegedly evaded taxes and intentionally destroyed accounting documents. State media also reports that Ai was granted bail on account of Ai's "good attitude in confessing his crimes", willingness to pay back taxes, and his chronic illnesses. According to the Chinese Foreign Ministry, he is prohibited from leaving Beijing without permission for one year. Ai's supporters widely viewed his detention as retaliation for his vocal criticism of the government. On 23 June 2011, professor Wang Yujin of China University of Political Science and Law stated that the release of Ai on bail shows that the Chinese government could not find any solid evidence of Ai's alleged "economic crime". On 24 June 2011, Ai told a Radio Free Asia reporter that he was thankful for the support of the Hong Kong public, and praised Hong Kong's conscious society. Ai also mentioned that his detention by the Chinese regime was hellish (Chinese: Jiu Si Yi Sheng ), and stressed that he is forbidden to say too much to reporters.  After his release, his sister gave some details about his detention condition to the press, explaining that he was subjected to a kind of psychological torture: he was detained in a tiny room with constant light, and two guards were set very close to him at all times, and watched him constantly. In November, Chinese authorities were again investigating Ai and his associates, this time under the charge of spreading pornography. Lu was subsequently questioned by police, and released after several hours though the exact charges remain unclear. In January 2012, in its International Review issue Art in America magazine featured an interview with Ai Weiwei at his home in China. J.J. Camille (the pen name of a Chinese-born writer living in New York), "neither a journalist nor an activist but simply an art lover who wanted to talk to him" had travelled to Beijing the previous September to conduct the interview and to write about his visit to "China's most famous dissident artist" for the magazine.  On 21 June 2012, Ai's bail was lifted. Although he is allowed to leave Beijing, the police informed him that he is still prohibited from traveling to other countries because he is "suspected of other crimes," including pornography, bigamy and illicit exchange of foreign currency. Until 2015, he remained under heavy surveillance and restrictions of movement, but continues to criticize through his work. In July 2015, he was given a passport and may travel abroad.
