As an example, there is an American author B.B.Alston whose popular books for children were translated into dozen languages.

He has a page on Polish Wikipedia: https://pl.wikipedia.org/wiki/B.B._Alston

But my attempts to make him a page on English Wikipedia keep getting rejected -- failed to establish notability. The fact that he won some awards and kids read his stories on the other side of the planet is apparently not good enough for Wikipedia.
