Even though the first mention of a village called Otwosko comes from the early 15th century, Otwock did not fully develop until the second half of the 19th century, when in 1877 the Vistula River Railroad was opened, which ran from Mława via Warsaw, to Lublin and Chełm. Otwock, which is located along the line, became a popular suburb, with numerous spas and several notable guests, including Józef Piłsudski and Władysław Reymont, who wrote his Nobel prize-winning novel Chłopi there. In 1916, Otwock was incorporated as a town and became the seat of a powiat. In 1936 railway connection Warsaw - Otwock was electrified as the first rail line in Poland.

Following the Nazi–Soviet Invasion of Poland in December 1939, the German authorities established a Jewish ghetto in Otwock. A murderous Action T4 euthanasia program was carried out by the Nazis in the local Zofiówka Sanatorium for the psychiatric patients[1] in order to confine its Jewish population for the purpose of persecution and exploitation.[2] The Ghetto was liquidated between August and 19 September 1942, when 75% of its Jewish population of 12,000–15,000 numbering at around 8,000 were assembled by the Nazis at a layover yard in Otwock (pictured) and transported in cattle trucks to extermination camps in Treblinka and Auschwitz.[3] Jews who remained were summarily shot at Reymonta Street soon after.[4]

Otwock is the hometown of Irena Sendler (1910 – 2008), the Polish humanitarian who saved thousands of Jewish children during the Holocaust; as well as Krystyna Dańko, both awarded the titles of Righteous among the Nations by Yad Vashem. Writer Calel Perechodnik, a Jewish Ghetto Policeman from Otwock also hailed from this town. Following the liberation, a children's home for Holocaust survivors was established in Otwock.[5]


In 1958, Ewa, the first Polish nuclear reactor was activated in Swierk district of Otwock. A second research reactor, Maria, was erected in 1974.
