Perhaps “Protector” or “Defensor”? Those Jews which Schindler rescued from the death camps did not know a full rescue until the end of WWII.

It´s true that "rescatador" as such sounds a bit weird if the surrounding context doesn´t help. It´s a bit ambiguous (rescatadores... ¿de qué?). But in this case the context available is key and clears out all possible doubts, I feel. Hence I see nothing wrong in using it in this context.

No, I didn't know. This is not my wheelhouse. I'm a native speaker of English. I'm asking the question on behalf of a person who raised a question about "rescatador" because of its other meaning. Also, a translator who is a native speaker of Argentine Spanish said she was not familiar with the word in the proposed context.

I have just read your explanation and do not understand your misgivings concerning "rescatador" in this context. You probably know that this term, "rescatador", is used as such by the Israel Ministry of Foreign Affairs on their web site when they refer to the "Righteous Among the Nations" ("Justos entre las naciones"). Please see here:

Well, I assume the Israeli people are entitled like nobody else to suggest a translation in this context (persecution in Nazi Germany).
You may consider "salvador" too, but I personally think that this word has a distinct religious touch that might not be suitable for this context. However, if you use “salvadores de judíos” the potential ambiguity disappears and the expression turns out fully acceptable to me.
