JF Ptak Science Books Quick Post
This was a surprise, finding M. Bollee's article (Sur une nouvelle machine a calculer) in the issue of an 1889 Comptes Rendus spread out in front of me, pecking around in that big 10-pound volume looking for something else not Bollee. It was very easy to miss this article if you weren't looking for it, just a few pages long in a 1000-page book. But there it was, nestled comfortably in pp 737-739. It these few pages Bollee describes his machine and with particular reference to his innovative approach to direct multipilication--a fine addition (ha!) to the long line of contributions by Babbage and Clement, Scheutz, Wiberg and Grant and Hamann.
Notes:
Léon Bollée: "Sur une nouvelle machine a calculer", in Comptes Rendus de l'Academie Sciences (Paris), volume 109, 1889, pp. 737-9. Offered in the original printed wrappers, removed from a larger bound volume.
