When something happens “on the low,“ you expect that not a lot of people have knowledge of it. But why do we say on the low? Is it because something is low-key, or is the story behind the phrase much more ornate? Could it be that there was a man named “Lowenthal“ who had a hand in creating the phrase we all know and love? Maybe when he touched things they turned invisible, hence if something was on top of Lowenthal, it might not be easily seen. This is all just speculation, of course, but an interesting possible backstory nonetheless.
