Kwame Nkrumah PC (21 September 1909 - 27 April 1972) was a Ghanaian politician and revolutionary. He was the first prime minister and president of Ghana, having led it to independence from Britain in 1957. An influential advocate of Pan-Africanism, Nkrumah was a founding member of the Organization of African Unity and winner of the Lenin Peace Prize in 1962. After twelve years abroad pursuing higher education, developing his political philosophy, and organizing with other diasporic pan-Africanists, Nkrumah returned to Gold Coast to begin his political career as an advocate of national independence.
Nkrumah returned to London in May 1945 and enrolled at the London School of Economics as a PhD candidate in anthropology. He withdrew after one term and the next year enrolled at University College, with the intent to write a philosophy dissertation on "Knowledge and Logical Positivism". His supervisor, A. J. Ayer, declined to rate Nkrumah as a "first-class philosopher", saying, "I liked him and enjoyed talking to him but he did not seem to me to have an analytical mind. He wanted answers too quickly. I think part of the trouble may have been that he wasn't concentrating very hard on his thesis. It was a way of marking time until the opportunity came for him to return to Ghana." Finally, Nkrumah enrolled in, but did not complete, a study in law at Gray's Inn.  Nkrumah spent his time on political organising. He and Padmore were among the principal organizers, and co-treasurers, of the Fifth Pan-African Congress in Manchester (15-19 October 1945). The Congress elaborated a strategy for supplanting colonialism with African socialism. They agreed to pursue a federal United States of Africa, with interlocking regional organizations, governing through separate states of limited sovereignty. They planned to pursue a new African culture without tribalism, democratic within a socialist or communist system, synthesizing traditional aspects with modern thinking, and for this to be achieved by nonviolent means if possible. Among those who attended the congress was the venerable W. E. B. Dubois along with some who later took leading roles in leading their nations to independence, including Hastings Banda of Nyasaland (which became Malawi), Jomo Kenyatta of Kenya, Obafemi Awolowo of Nigeria, and C. L. R. James.  The congress sought to establish ongoing African activism in Britain in conjunction with the West African National Secretariat (WANS) to work towards the decolonization of Africa. Nkrumah became the secretary of WANS. In addition to seeking to organise Africans to gain their nations' freedom, Nkrumah sought to succor the many West African seamen who had been stranded, destitute, in London at the end of the war, and established a Coloured Workers Association to empower and succor them. The U.S. State Department and MI5 watched Nkrumah and the WANS, focusing on their links with Communism. Nkrumah and Padmore established a group called The Circle to lead the way to West African independence and unity; the group aimed to create a Union of African Socialist Republics. A document from The Circle, setting forth that goal, was found on Nkrumah upon his arrest in Accra in 1948, and was used against him by the British authorities.

Williams was born on April 5, 1973, in Virginia Beach, Virginia, the oldest of three sons of Pharaoh Williams, a handyman, and his wife Carolyn, a teacher. His roots extend for generations in Virginia and North Carolina, and one of his ancestors journeyed to West Africa in 1831, prompting other relatives to emigrate from America to Liberia in 1832. He met Chad Hugo in a seventh-grade summer band camp where Williams played the keyboards and drums and Hugo played tenor saxophone. They were also both members of a marching band; Williams played the snare drum while Hugo was drum major.
On March 31, 2014, Williams was announced as a new coach for the seventh season of The Voice, replacing CeeLo Green. On May 18, 2015, Team Pharrell had 16-year-old Sawyer Fredericks win the eighth season of The Voice. In June 2014, it was announced that Williams would make a guest appearance on the docu-series Sisterhood of Hip Hop. Williams was the executive producer of Atlanta rapper T.I.'s ninth studio album, Paperwork, which was released on October 21, 2014 by Grand Hustle and Columbia Records. In May 2014, Williams curated an art show named after his album, "Girl," at the Galerie Perrotin in Paris, France. The show included 37 artists including Takashi Murakami, JR, Daniel Arsham, and Marina Abramovic among others." Comme des Garcons developed a unisex fragrance with Williams scheduled for release in late 2014. Kaws designed the bottle artwork.  In January 2015, Williams and Al Gore announced that they are teaming up to create a 7-continent "Live Earth" concert on June 18 to raise awareness about and pressure governments to act on climate change. He is the musical director. On February 8, 2015, Williams made a cameo in an episode of The Simpsons entitled "Walking Big & Tall" where he comes to Springfield to write a new anthem for the town. Williams recorded three songs for the soundtrack to the animated film The SpongeBob Movie: Sponge Out of Water. He also recorded a song "Shine" with Gwen Stefani for the Paddington movie. At the 2015 Grammy Awards Williams performed an orchestral rendition of "Happy" with composer Hans Zimmer and pianist Lang Lang that included a tribute to the Black Lives Matter "Hands Up, Don't Shoot" movement inspired by Eric Garner's death and the events in Ferguson, Missouri. In 2015, a unanimous jury determined that Williams's 2013 hit song "Blurred Lines" was an infringement of the 1977 Marvin Gaye song "Got to Give It Up". The jury awarded the Gaye family $7.4 million in damages for the copyright infringement based on profits generated.  In October 2015, the Tisch School of the Arts at New York University named Williams as their artist-in-residence. He gave the 2017 commencement address at NYU and received an honorary degree on May 17, 2017.  Also in October 2015, Williams announced that he will perform with a gospel choir on Sunday, November 1, at Emanuel AME Church in Charleston, South Carolina, where nine black parishioners were shot and killed on June 17, allegedly by a young white man who is awaiting trial. This is part of a program on race relations being produced by A+E Networks and iHeartMedia. Williams plans to speak with community leaders and others affected by the shooting, which dominated the U.S. news media for several days. The two-hour Shining a Light: A Concert for Progress on Race in America program is scheduled to air November 20, and will also feature a concert to be filmed November 18 in Los Angeles. A goal of the program is to raise money for the victims of racial violence and for organizations around the country working to promote racial equity.
