A Study by Czerniak(?)

To my surprise, a recent Chess Cafe's endgame studies column [opens as pdf file] happened to show an ending by "M. Czerniak" (Ending #709 they published, reproduced below with their information about the source). Note that the pdf file includes the long and interesting solution to the study, as well.

Presumably this is the same Moshe Czerniak who later became Israel's "Mr. Chess"; but nowhere have I heard of him ever composing studies or problems. Of course I may be wrong and it's a different Czerniak, but that seems unlikely.

Is anything else known about Czerniak as a composer?
