1. Rosa Luxemburg (1871 - 1919)

With an HPI of 86.39, Rosa Luxemburg is the most famous Polish Social Activist.  Her biography has been translated into 126 different languages on wikipedia.

Rosa Luxemburg (Polish: [ˈruʐa ˈluksɛmburk] (listen); German: [ˈʁoːza ˈlʊksəmbʊʁk] (listen); Polish: Róża Luksemburg; also Rozalia Luksenburg; 5 March 1871 – 15 January 1919) was a Polish Marxist economist, anti-war activist and revolutionary socialist. Successively, she was a member of the Social Democracy of the Kingdom of Poland and Lithuania (SDKPiL), the Social Democratic Party of Germany (SPD), the Independent Social Democratic Party (USPD) and the Communist Party of Germany (KPD). Born and raised in a Jewish family in Poland, she became a German citizen in 1897. After the SPD supported German involvement in World War I in 1915, Luxemburg and Karl Liebknecht co-founded the anti-war Spartacus League (Spartakusbund) which eventually became the KPD. During the November Revolution, she co-founded the newspaper Die Rote Fahne (The Red Flag), the central organ of the Spartacist movement. Luxemburg considered the Spartacist uprising of January 1919 a blunder, but supported the attempted overthrow of the government and rejected any attempt at a negotiated solution. Friedrich Ebert's majority SPD government crushed the revolt and the Spartakusbund by sending in the Freikorps, government-sponsored paramilitary groups consisting mostly of World War I veterans. Freikorps troops captured and summarily executed Luxemburg and Liebknecht during the rebellion. Due to her pointed criticism of both the Leninist and the more moderate social democratic schools of socialism, Luxemburg has had a somewhat ambivalent reception among scholars and theorists of the political left. Nonetheless, Luxemburg and Liebknecht were extensively idolized as communist martyrs by the East German communist government. The German Federal Office for the Protection of the Constitution asserts that idolization of Luxemburg and Liebknecht is an important tradition of the German far-left. Despite her own Polish nationality and strong ties to Polish culture, opposition from the PPS due to her stance against the creation of a bourgeois Polish state and later criticism from Stalinists have made her a controversial historical figure in Poland's present-day political discourse.

2. Irena Sendler (1910 - 2008)

With an HPI of 80.97, Irena Sendler is the 2nd most famous Polish Social Activist.  Her biography has been translated into 57 different languages.

Irena Stanisława Sendler (née Krzyżanowska), also referred to as Irena Sendlerowa in Poland, nom de guerre Jolanta (15 February 1910 – 12 May 2008), was a Polish humanitarian, social worker, and nurse who served in the Polish Underground Resistance during World War II in German-occupied Warsaw. From October 1943 she was head of the children's section of Żegota, the Polish Council to Aid Jews (Polish: Rada Pomocy Żydom).In the 1930s, Sendler conducted her social work as one of the activists connected to the Free Polish University. From 1935 to October 1943, she worked for the Department of Social Welfare and Public Health of the City of Warsaw. During the war she pursued conspiratorial activities, such as rescuing Jews, primarily as part of the network of workers and volunteers from that department, mostly women. Sendler participated, with dozens of others, in smuggling Jewish children out of the Warsaw Ghetto and then providing them with false identity documents and shelter with willing Polish families or in orphanages and other care facilities, including Catholic nun convents, saving those children from the Holocaust.The German occupiers suspected Sendler's involvement in the Polish Underground and in October 1943 she was arrested by the Gestapo, but she managed to hide the list of the names and locations of the rescued Jewish children, preventing this information from falling into the hands of the Gestapo. Withstanding torture and imprisonment, Sendler never revealed anything about her work or the location of the saved children. She was sentenced to death but narrowly escaped on the day of her scheduled execution, after Żegota bribed German officials to obtain her release. In post-war communist Poland, Sendler continued her social activism but also pursued a government career. In 1965, she was recognised by the State of Israel as Righteous Among the Nations. Among the many decorations Sendler received were the Gold Cross of Merit granted her in 1946 for the saving of Jews and the Order of the White Eagle, Poland's highest honour, awarded late in Sendler's life for her wartime humanitarian efforts.

3. Ferdinand Lassalle (1825 - 1864)

With an HPI of 76.68, Ferdinand Lassalle is the 3rd most famous Polish Social Activist.  His biography has been translated into 51 different languages.

Ferdinand Lassalle (German: [laˈsal]; 11 April 1825 – 31 August 1864) was a Prussian-German jurist, philosopher, socialist and political activist best remembered as the initiator of the social democratic movement in Germany. "Lassalle was the first man in Germany, the first in Europe, who succeeded in organising a party of socialist action", or, as Rosa Luxemburg put it: "Lassalle managed to wrestle from history in two years of flaming agitation what needed many decades to come about." As agitator he coined the terms night-watchman state and iron law of wages.

His character was engraved as a symbol of courage and sacrifice, and to this day his image represents Jewish resistance during the Holocaust.

5. Leopold Trepper (1904 - 1982)

With an HPI of 68.60, Leopold Trepper is the 5th most famous Polish Social Activist.  His biography has been translated into 19 different languages.

Leopold Zakharovitch Trepper (23 February 1904 – 10 January 1982) was a Polish Communist and career Soviet agent of the Red Army Intelligence. With the code name Otto, Trepper had worked with the Red Army since 1930. He was also a resistance fighter and journalist.Trepper and Richard Sorge, a Soviet military intelligence officer, were the two main Soviet agents in Europe and were employed as roving agents to set up espionage networks throughout Europe and in Japan. While Sorge was a penetration agent, Trepper ran a series of clandestine cells for organising agents in Europe. Trepper used the latest technology at the time—small wireless radios—to communicate with Soviet intelligence. Although the Funkabwehr's monitoring of the radios transmission eventually led to the destruction of Treppers organisation, this sophisticated use of the technology-enabled the espionage organisation to behave as a network with the ability to achieve tactical surprise and deliver high-quality intelligence, such as the warning of Operation Barbarossa.In 1936, Trepper became the technical director of a Soviet Red Army Intelligence unit in western Europe. He was responsible for recruiting agents and creating espionage networks. Trepper was an experienced intelligence officer, and an extremely resourceful and capable man completely at home in the west. He was a man who could not be drawn in conversation, who lived a reclusive life, and had a talent of judging people that enabled him to easily penetrate significant groups. By the start of World War II, Trepper controlled a large espionage network in Belgium, that had links with Dutch, German and Swiss agents and operated seven separate espionage networks in France. His operation was known as the Red Orchestra to the Abwehr.

6. Jan Karski (1914 - 2000)

With an HPI of 68.49, Jan Karski is the 6th most famous Polish Social Activist.  His biography has been translated into 22 different languages.

Jan Karski (24 June 1914 – 13 July 2000) was a Polish soldier, resistance-fighter, and diplomat during World War II. He is known for having acted as a courier in 1940–1943 to the Polish government-in-exile and to Poland's Western Allies about the situation in German-occupied Poland. He reported about the state of Poland, its many competing resistance factions, and also about Germany's destruction of the Warsaw Ghetto and its operation of extermination camps on Polish soil that were murdering Jews, Poles, and others. Emigrating to the United States after the war, Karski completed a doctorate and taught for decades at Georgetown University in international relations and Polish history. He lived in Washington, D.C., to the end of his life. He did not speak publicly about his wartime missions until 1981, when he was invited as a speaker to a conference on the liberation of the camps. Karski was featured in Claude Lanzmann's nine hour film Shoah (1985), about the Holocaust, based on oral interviews with Jewish and Polish survivors. After the fall of the Soviet Union, Karski was honored by the new Polish government, as well as being honored in the US and European nations for his wartime role. In 2010 Lanzmann released a short documentary, The Karski Report, which contained more about Karski's meetings with President Franklin D. Roosevelt and other US leaders in 1943.Karski later stated: "I wanted to save millions, and I was not able to save one man."

7. Jan Gotlib Bloch (1836 - 1902)

With an HPI of 65.00, Jan Gotlib Bloch is the 7th most famous Polish Social Activist.  His biography has been translated into 20 different languages.

For the sexologist Ivan Bloch, see Iwan BlochJan Gotlib (Bogumił) Bloch (Russian: Иван Станиславович Блиох or Блох) (July 24, 1836, Radom – December 25, 1901/1902, Warsaw) was a Polish banker and railway financier who devoted his private life to the study of modern industrial warfare. Born Jewish and a convert to Calvinism, he spent considerable effort to opposing the prevalent Antisemitic policies of the Tsarist government, and was sympathetic to the fledgling Zionist Movement. Bloch had studied at the University of Berlin, worked at a Warsaw bank and then moved to St. Petersburg, capital of the Russian Empire (which governed much of the Polish lands at the time). There, he took part in the development of the Russian Railways, both in financing the construction of new railways and in writing research papers on the subject. He founded several banking, credit and insurance companies. In 1877 he was appointed a member of the Russian Finance Ministry's Scientific Committee.

8. Ryszard Siwiec (1909 - 1968)

With an HPI of 64.82, Ryszard Siwiec is the 8th most famous Polish Social Activist.  His biography has been translated into 21 different languages.

Ryszard Siwiec (Polish pronunciation: [ˈrɨʂart ˈɕivjɛt͡s]; 7 March 1909 – 12 September 1968) was a Polish accountant and former Home Army resistance member who was the first person to commit suicide by self-immolation in protest against the Warsaw Pact invasion of Czechoslovakia. Although his act was captured by a motion picture camera, Polish press omitted any mention of the incident, which was successfully suppressed by the authorities. Siwiec prepared his plan alone, and few people realized what he tried to achieve with his sacrifice. His story remained mostly forgotten until the fall of communism, when it was first recounted in a documentary film by Polish director Maciej Drygas. Since then, Siwiec has been posthumously awarded a number of Czech, Slovak, and Polish honors and decorations. Siwiec's death foreshadowed the much better known self-immolation of Jan Palach in Prague four months later. Siwiec was the first person from Central and Eastern Europe to self-immolate in protest of the invasion, and one of three in Polish history (the other being Walenty Badylak and Piotr Szczęsny).

9. Ernestine Rose (1810 - 1892)

With an HPI of 54.34, Ernestine Rose is the 9th most famous Polish Social Activist.  Her biography has been translated into 15 different languages.

Ernestine Louise Rose (January 13, 1810 – August 4, 1892) was a suffragist, abolitionist, and freethinker who has been called the “first Jewish feminist.” Her career spanned from the 1830s to the 1870s, making her a contemporary to the more famous suffragists Elizabeth Cady Stanton and Susan B. Anthony. Largely forgotten in contemporary discussions of the American women's rights movement, she was one of its major intellectual forces in nineteenth-century America. Her relationship with Judaism is a debated motivation for her advocacy. Although less well remembered than her fellow suffragists and abolitionists, in 1996, she was inducted into the National Women's Hall of Fame, and in 1998 the Ernestine Rose Society was founded to “revive the legacy of this important early nineteenth century reformer by recognizing her pioneering role in the first wave of feminism.”
