I believe that Aleph null was invented by Georg Cantor for use in discussing the orders of different infinite sets. Cantor developed Cardinal numbers which could be used to denumerate infinite sets in the same way that natural numbers are used to denumerate finite sets. For instance, Cantor showed that the set of real numbers contains more elements than the set of natural numbers, despite the fact that both sets are infinite. Aleph Null is the lowest cardinal number, sort of like one is the lowest natural number.
