This title, which the State of Israel gives to non-Jews who risked their lives to save Jews during World War Two was bestowed on Crndic and Lang posthumously.
The presentation of the titles began in 1963 and so far over 21,310 non-Jews have been proclaimed the Righteous Among the Nations, including 105 persons from Croatia, the Israeli Ambassador to Zagreb, Shmuel Meirom, said in the Croatian capital on Friday .
"We are here today to show you that during World War Two not only brutality and ruthlessness ruled. Dangerous ideas still exist somewhere and to prevent barbarism we must educate young people and teach them to discard discrimination on the basis of somebody's religion, race or ideology," the ambassador said.
Attending the Zagreb ceremony, Croatian President Stjepan Mesic said that not one criminal or crime should remain uninvestigated and unpunished.
Mesic added that the Holocaust was a unique crime which must never be relativised or negated.
The Jews have the right to peacefully live in their own state. Somebody may not agree with this or that aspect of the Israeli politics, but there is no reason for justifying calls for the annihilation of the State of Israel, Mesic said.
Stefanija Podolski thanked for the award and on this occasion she related how she had helped the mother and her six children from the Jewish family Schnittlinger to save their lives in April 1941.
Anka Crndic, who died in 1972, helped the wife and two sons of lawyer Rikard Steiner from the town of Koprivinica to flee into the Italian occupation zone.
Ljubica Lang saved Feja Frank and her mother from the Ustasha-run camp in the town of Bjelovar.
The names of Lang, Crndic and Podolski will be engraved on marble plaques in The Garden of the Righteous Among the Nations within the Yad Vashem complex in Jerusalem.
