Kim Il-sung (15 April 1912 – 8 July 1994) was the leader of the Democratic People's Republic of Korea, commonly referred to as "North Korea", from its establishment in 1948 until his death in 1994. He held the posts of Prime Minister from 1948 to 1972 and President from 1972 to his death. He was also the leader of the Workers' Party of Korea from 1949 to 1994 (titled as chairman from 1949 to 1966 and as general secretary after 1966).

His tenure as leader of North Korea has often been described as autocratic, and he established an all-pervasive cult of personality. From the mid-1960s, he promoted his self-developed Juche variant of communist national organization, which later replaced Marxism-Leninism as the ideology of the state in 1972. In the Library of Congress Country Study on North Korea in 2009, he was described as "one of the most intriguing figures of the twentieth century". He outlived Joseph Stalin by four decades, Mao Zedong by two, and remained in power during the terms of office of six South Korean presidents, 7 Soviet leaders, ten U.S. presidents, and twenty-one Japanese prime ministers.

Mao Zedong, also transliterated as Mao Tse-tung  listen (help·info), and commonly referred to as Chairman Mao (December 26, 1893 – September 9, 1976), was a Chinese Communist revolutionary, guerrilla warfare strategist, Marxist political philosopher, and leader of the Chinese Revolution. He was the architect and founding father of the People's Republic of China (PRC) from its establishment in 1949, and held authoritarian control over the nation until his death in 1976. His theoretical contribution to Marxism–Leninism, along with his military strategies and brand of policies, are collectively known as Maoism.

Mao rose to power by commanding the Long March, forming a Second United Front with Kuomintang (KMT) during the Second Sino-Japanese War to repel a Japanese invasion, and leading the Communist Party of China (CPC) to victory against Generalissimo Chiang Kai-shek's Kuomintang (KMT) in the Chinese Civil War. After solidifying the reunification of China through his Campaign to Suppress Counterrevolutionaries, Mao enacted sweeping land reform, by using violence and terror to overthrow the feudal landlords before seizing their large estates and dividing the land into people's communes. During the years when Mao was China’s 'Great Helmsman', a range of positive changes came to China. These included promoting the status of women, improving popular literacy, doubling the school population, providing universal housing, abolishing unemployment and inflation, increasing health care access, and dramatically raising life expectancy. In addition, China's population almost doubled during the period of Mao's leadership (from around 550 to over 900 million). As a result, Mao is still officially held in high regard by many in China as a great political strategist, military mastermind, and savior of the nation. Maoists further promote his role as a theorist, statesman, poet, and visionary, while anti-revisionists continue to defend most of his policies.

Kim Jong-il (born Yuri Irsenovich Kim; 16 February 1941; official biography claims 1942 – 17 December 2011) was the supreme leader of North Korea (DPRK) from 1994 to 2011. He succeeded his father and founder of the DPRK Kim Il-sung following the elder Kim's death in 1994. Kim Jong-il was the General Secretary of the Workers' Party of Korea, Chairman of the National Defence Commission of North Korea, and the supreme commander of the Korean People's Army, the fourth-largest standing army in the world.

In April 2009, North Korea's constitution was amended to refer to him as the "supreme leader". He was also referred to as the "Dear Leader", "our Father", and "the General", among others. His son Kim Jong-un was promoted to a senior position in the ruling Workers' Party and is his successor. In 2010, he was ranked 31st in Forbes Magazine's List of The World's Most Powerful People. The North Korean government announced his death on 19 December 2011.

Following his demise, he was succeeded by his third son Kim Jong-un. He was proclaimed the Eternal General Secretary of the Workers' Party of Korea and Eternal Chairman of the National Defence Commission in 2012. His birthday is a public holiday in the country.

Isang Yun (also spelled Yun I-sang; 17 September 1917 - 3 November 1995) was a Korean-born composer who made his later career in Germany.

Yun was born in Chungmu City, Korea (now absorbed into Tongyeong in present day South Korea) in 1917, the son of poet Yun Ki-hyon. He began writing music at the age of 14, and began studying music formally two years later, in 1933. He studied at the Osaka Conservatory, and composition under Tomojiro Ikenouchi in Tokyo from 1938. After Japan entered World War II, he moved back to Korea and participated in the Korean independence movement. He was captured and imprisoned by the Japanese in 1943.

After the war, he did welfare work, establishing an orphanage for war orphans, and teaching music in Tongyeong and Busan. After the armistice ceasing hostilities in the Korean War in 1953, he began teaching at the Seoul National University. He received the Seoul City Culture Award in 1955, and traveled to Europe the following year to finish his musical studies.

In Paris (till 1957) and West Berlin (1957-59), he studied composition under Tony Aubin, Pierre Revel, Boris Blacher, Josef Rufer, and Reinhard Schwarz-Schilling. In 1958 he attended the International Summer Courses of Contemporary Music in Darmstadt, and began his career in Europe with premieres of his Music for Seven Instruments in Darmstadt and Five Pieces for Piano in Bilthoven. The premiere of his oratorio Om mani padme hum in Hanover 1965 and Réak in Donaueschingen 1966 gave him international renown. With "Réak" he introduced the sound idea of Chinese-Korean ceremonial music as well as the East Asian mouth organ ssaeng-hwan (Korean), sheng (Chinese), or shô (Japanese) into Western avantgarde music.

James Earl "Jimmy" Carter, Jr. (born October 1, 1924) is an American politician who served as the 39th President of the United States (1977–1981) and was the recipient of the 2002 Nobel Peace Prize, the only U.S. President to have received the Prize after leaving office. Before he became President, Carter served as a U.S. Naval officer, was a peanut farmer, served two terms as a Georgia State Senator and one as Governor of Georgia (1971–1975).

During Carter's term as President, two new cabinet-level departments were created: the Department of Energy and the Department of Education. He established a national energy policy that included conservation, price control, and new technology. In foreign affairs, Carter pursued the Camp David Accords, the Panama Canal Treaties, the second round of Strategic Arms Limitation Talks (SALT II), and returned the Panama Canal Zone to Panama. Throughout his career, Carter strongly emphasized human rights. He took office during a period of international stagflation, which persisted throughout his term. The end of his presidential tenure was marked by the 1979–1981 Iran hostage crisis, the 1979 energy crisis, the Three Mile Island nuclear accident, the Soviet invasion of Afghanistan (at the end of 1979), 1980 Summer Olympics boycott by the United States of the Moscow Olympics and the 1980 eruption of Mount St. Helens.
