Welcome. This page points you to to several of my interests, including Temple Beth Shalom, APUA, the HaYom Hebrew Calendar, papers by me on various topics including breastfeeding economics and cryptography, the Math in the Movies page, history of early computers (I go way back!), and books I've coauthored. I contribute to Wikipedia from time to time under the user name ArnoldReinhold.

Reinhold's Papers The Internet is the ultimate vanity press. This
page includes stuff you might find interesting that I have written on
cryptography, early computing, immunology, space exploration,
mathematics, and childcare. It also points to books I have
co-authored. Also see my
page at Researchgate for a more up-to-date list.

Arnold's
Computer History Collection The early history of computers is in
danger of being lost as obsolete equipment is scrapped, old files are
discarded and computing pioneers submit their last jobs at the great
machine room in the sky. The information presented here is based
mainly on my personal recollections and on original material that I
own. I hope to add more when I have time. There is a lot to tell. I
have also been editing Wikipedia articles on computer history and
uploading historic photos.
Thanks for stopping by!
