I miss Walt. I first got acquainted with Sphere Research through slide
rules. I had saved mine from my university days. I still have the Dietzgen
N1725 Vector Log Log. My father was an architect and bought it for me at a
discount since the firm he worked for had a contract with Dietzgen for
drafting instruments. That slide rule got me through p-chem. I only used
the hyperbolic scales to see how they worked. I did use most of the others
for homework problems.
A lot of my collection came from Sphere Research - new-in-the-box Pickett
rules including their famous N4, also a vector log log. I have one of those
nuclear bomb effects circular slide rules and got it in the book ¡°The
Effects of Nuclear Weapons¡± but on eBay, not from Walt. Since then, I also
found a Soviet version. Being a radiologist, I thought that understanding
the dangers of the radiation from these weapons was something I should know
about.
It was only later that I started buying electronics from Walt. He was
always generous and would include a bonus bag of parts. Most were far
better than the usual ¡°floor sweeping¡± sorts of stuff; a lot of usable
parts in those bags.
I¡¯m sad that he¡¯s gone but glad Susan carries on. The effects of his years
of catering to many of those in this group are probably well known since
I¡¯m sure many of you would turn your browser to his site the minute his
¡°Stuff Day¡± announcements appeared.

That was a nicely done bio.
