Here's the additional info I promised. This was published in "Magic Without Apparatus", by Camille Gualtier:
Mr. de Biere was the first to show us, at a private meeting, the vanish of the rest of the pack by the aid of a fan of cards, which we have since seen performed in public, notably by Nate Leipzig at the Theatre des Folies-Marigny and again last winter by Allan Shaw at the Olympia in Paris.
The original book, "La Prestidigitation sans Appareils" was first published in France in 1914, so that will give an approximate date for this. As I noted earlier, Leipzig was in France in 1906 and 1907, so that would have been when he was demonstrating it.
