French is my native language and I speak and write it way better than the average francophone, IMHO...
As for English, I'm pretty fluent in it but, just to be on the safe side, I have English-speaking friends proof-read important documents. The memorial was such a case.
As for German and Spanish, I had to rely on third-parties.
I do use Google translate on occasion, but in this case, I relied entirely on good friends. It was their native language but, as for their mastery of their own grammar...
If you have a better translation to offer, do so, I don't mind. Whenever a new update is made, I would make the correction.
