Re: John von Neumann 

It does not fit in with other articles in this category: 3D Life, Block cellular automaton, Cellular automaton, Cellular image processing, Codd's cellular automaton, Conway's Game of Life, Day & Night, to name but a few. Generally speaking, the CA category appears to be divided between examples of cellular automata (Immigration (CA), QuadLife, Rule 110 cellular automaton) and terms related to cellular automata (Garden of Eden pattern, Gun (CA), Oscillator (CA)) - to such an extent that it might be best to divide this category into two subcategories. What you don't find in this category, however, are people who have contributed to cellular automata, regardless of their distinction. What we can do, however - I'll be glad to contribute, and it'd be nice if you helped to - is possibly create a subcategory, "Scientists who have made a major contribution to cellular automata" (or, for preference, a shorter name, if you can come up with one), and in this category place Mr von Neumann. Tell me what you think. —
