Not related to the guy at all.... Loved the book, "Mrs. Frisby and the Rats of NIMH" when I was a kid. I see echoes of his work everywhere from my childhood though. Or was overpopulation just in the 70's Zeitgeist with movies like "Soylent Green", etc? I remember a traveling demonstration presented to us in grade school. Some guy arrived with a kind of computer (this being the early 70's). He set it up on a desk (and if I am remembering correctly, it may have been kind of vertical ... and say the size of a Pachinko machine). I believe it was some kind of custom, single-purpose, machine. In my fuzzy recollection it had knobs that could control rates of population growth, perhaps controls on resources, etc. The operator would adjust the knobs and the machine then seemed to give dire predictions of the future. Now go and enjoy recess, kids.
