20th-century political scientists

James Alfred Perkins (October 11, 1911 – August 19, 1998) was an American academic administrator who was the seventh president of Cornell University, from 1963 to 1969.

Arthur Doak Barnett (October 8, 1921, Shanghai – March 17, 1999 Washington, D.C.), known as A. Doak Barnett, was an American journalist, political scientist, and public figure who wrote about the domestic politics and the foreign relations of China and United States-China relations. He published more than 20 academic and public interest books and edited still others. Barnett's parents were missionaries in China, and Barnett used his Chinese language ability while travelling widely in China as a journalist before 1949. He grounded his journalism and his scholarship in exact detail and clear language. Starting in the 1950s, when there were no formal diplomatic relations between the United States and the People's Republic of China, he organized public outreach programs and lobbied the United States government to put those relations on a new basis.
Barnett taught at Columbia University from 1961–1969, then went to the Brookings Institution in 1969. In 1982, he was named the George and Sadie Hyman Professor of Chinese Studies at the Paul H. Nitze School of Advanced International Studies at the Johns Hopkins University in Washington, D.C.

Johannes Agnoli (22 February 1925 in Valle di Cadore, Eastern Dolomites – 4 May 2003 in San Quirico di Moriano near Lucca) was an Italian Marxist political scientist, though he rejected the label Marxist, preferring instead - somewhat ironically - to call himself an Agnolist.

Richard Montgomery Scammon (July 17, 1915 – April 27, 2001) was an American author, political scientist and elections scholar. He served as Director of the U.S. Bureau of the Census from 1961 to 1965. Afterwards, he worked for decades directing election analysis for NBC News.

Wolfgang Walter Arnulf Abendroth (2 May 1906 – 15 September 1985) was a German socialist, jurist, and political scientist. He was born in Elberfeld, now a part of Wuppertal in North Rhine-Westphalia. Abendroth was a radical social democrat and an important contributor to the constitutional foundation of post-World War II West Germany. In 1943 he was forcibly drafted into one of the 999th Division's "probation units" and while stationed in Greece he deserted to the Greek People's Liberation Army (ELAS). After the war he briefly held a Law professorship in East Germany. However, in 1948 he left for West Germany with his family, refusing to disassociate himself from the Social Democratic Party and join the, overwhelmingly stalinist, Socialist Unity Party of Germany (SED) which in 1949 became the ruling party of East Germany. In 1950 he was appointed professor of Political Science at Marburg and also served as a senior judge in the state court of Hesse. In 1961 he was expelled from the Social Demoractic Party for refusing to disassociate himself from the Socialist German Student Union (SDS). Due to his socialist principles and politics Abendroth was for many years after the end of the war under surveillance by West Germany's Intelligence services. First, by the CIA-affiliated, anti-communist, Gehlen Organisation and later, after 1956, by the German Federal Intelligence Service (BND) both of which were led by Reinhard Gehlen, a prominent Nazi before and during World War II.
