Bob Otnes … an appreciation The recent news that Bob Otnes has relinquished editorship of the JOS for personal reasons brings us to the end of an era, and what an era it has been. It has not always been obvious as to why the JOS followed the strategy for publishable material that it did, but 1 Skid Stick Issue 33 October 2009 New Members & Directory Each display panel is illustrated in full colour on the right hand pages with a brief Changes description of the numbered slide rules on the left.

The catalogue presentation is sensible and logical, the information is laid out clearly in both German and English without being fiddly or difficult and it does cover all aspects of “Models, Types and Scales” as the book’s sub-title declares. It clarified quickly and simplified doubts I had about a number of examples within my own collection. I must also compliment the author and his team; there are few (if any) typos or grammatical nonsense which makes using it an added pleasure. 2 Skid Stick Issue 33 October 2009 Specifically excluded are the Faber- What Would be Your Reaction Castell war production slide rules (labelled “hel”) which is a shame, and possibly the “Early Examples” could have been expanded to cover the obvious variants with gold lettering and so on. Peter also sensibly makes no attempt to cover any “mysterious” F-C slide rules that are known to exist, such as the Hemmi’s in F-C boxes with F-C back papers and cursor. Nor does he try and resolve any of the other un-resolved “weirdies” such as the claim for the 1/60/360 in an F-C instruction book that “This slide rule which is made in five sizes 4”, 5”, 6”, 10” and 20” ….”. These points are minor and really picky and in no way detract from a very fine piece of work. This is an excellent reference work which I can absolutely and unhesitatingly recommend as the definitive guide to these Makers and should be part of any slide rule collector’s library. Go and buy it tomorrow! “Great news, the burglars only took your This book is modestly priced at €15 stupid slide rules” (Europe), €20 (Worldwide) Peter Hopp Heaven forbid that this situation should happen to any member of the UKSRC, Gazette 10, Autumn 2009 but what would be your reaction should your better half come up with such pearls of wisdom? Answers to Hon Ed or PMH please! The Slide Rule Museum http://www.sliderulemuseum.com Mike Konshak’s on-line International Slide Rule Museum has been mentioned before in Skid Stick, and I would strongly recommend another look. It has obviously been growing over the recent past, not least in the ‘Historical Photos, People with SRs’ gallery which has Our 10th Anniversary Issue of the over 200 pictures of People and Slide Rules, Gazette is now available, with as, usual over but also in the ‘SR Who’s Who, Past and one hundred pages of interesting and diverse Present’ gallery where brief biographies and articles too numerous to mention. Copies pictures of slide rule luminaries are presented. available from the Hon. Ed. or via the 2010 membership subscription form (enclosed) I was especially delighted to find two Price inc. p&p £13.00 (UK), £16.00 images I have been hunting for a long time. (Europe), £18.00 (rest of world). Firstly, a picture of someone actually wearing a slide rule, (see Skid Stick 26, “Holstered slide Joint Slide Rules rules” Fact or fantasy?) the 1962 painting of Peter M Hopp, C. Eng., M.B.C.S. Frederick Emmons Terman, (1900–1986) complete with slide rule at waist. Terman is credited with being the father of Silicon Valley, any dude who wears a slide rule like that has to be worth knowing! Secondly, a picture of Sergei Korolev, (1906–1965) the father of the Soviet Space industry which I have been aware of but have never seen. There are a multitude of other interesting pictures of “People and Slide Rules”, I hope to be working with Mike rather than competing in this area. 3 Skid Stick Issue 33 October 2009 Further Mysteries solved - perhaps! “Hale’s Slide Rule” “Barron’s Calculating Rule” Peter Hopp C.N. Pickworth’s “The Indicator Handbook” part II (2nd edn. 1904), (being used for my ongoing search for planimeter and related data), has a description of Hale’s Slide Rule for indicator diagrams (see SS27, October 2007, page 5). The original Skid Stick article should have given us a clue. It noted that the price of the rule from the 1898 Stanley catalogue, in a case, was 4/- compared with other slide rules at anything between £1/- and £2/18/- for a 50cm Gravet rule.
