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 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. I also offer a range of consulting services.

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.

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!
