Sendler was a social worker who smuggled Jewish children out of the Warsaw Ghetto during World War II, when Poland was occupied by Nazi Germany. The children were placed with Christian families and in convents and given new names. Sendler died in 2008.
President Bronislaw Komorowski and Warsaw Mayor Hanna Gronkiewicz-Waltz presided over the naming ceremony last week. Sendler's daughter Janina Zgrzembska was also present.
