Bob Pease died in a car accident- honor him Tuesday

June 20, 2011

Here is the bad news from analog editor Bill Schweber:

Analog expert Bob Pease dies in accident

I talked it over with Jim Williams wife and she feels it would be fine to honor both Jim and Bob Pease at our celebration of life Tuesday, June 21, 2011. Bob Pease’s wife Nancy is flying in from Cape Cod that day and should be there a bit late, perhaps 7:30, but please come and offer your condolences.

[update] OK, my obit just went live:

Analog engineering legend Bob Pease killed in car crash

 Here is a section we cut out since it was too long:

The wild days of analog design

Bob Pease goes back to the wild days of analog design. This is when a core group of passionate engineers and scientist would work hard, play hard, and do as they pleased. Nobody knew what breakthrough would come next. They all knew that they had to work a furious pace lest their company be bested by one down the road. Dennis Monticelli, a fellow at National Semiconductor talks about turning down Intel to take a job with National back in 1975. “They couldn’t believe that any engineer would not want to work on memory and digital chips,” he relates. “The thing is, all the excitement and real passion was in analog, and it still is.”

How passionate are these analog folks? One story about Bob Pease comes to mind. It was 15 or 20 years ago. National was spinning a new mixed-signal group out of the amplifier group where Bob was an application engineer. Over the course of a week, engineers assigned to that new group would come into the amplifier lab and take some test equipment, all with manager’s approval. One day, two guys showed up and began to wheel away a large temperature tester, a so-called “elephant” due to the trunk-like nature of its air-output duct. Pease saw them pushing the elephant out the door and exclaimed “What’s next?! Our pants?!” He then whipped off his trousers and threw them up to the ceiling, where they poetically hooked onto a fire sprinkler head. They were in easy reach, Bob could have just pulled them down, but he was way too incensed. So he left the lab and went looking for his boss in the cubicles. Thankfully his boss was not at his desk, so Bob, still in his underwear, and still fuming, started off to the parking lot to just drive home in a huff. A concerned employee told Bob’s friend and mentor Martin Giles, the guy who put on the analog seminars. Martin saw that Bob was in the parking lot and said “Well, let’s just let him go, it’s better than bringing him back into the building wearing his underwear.” It is hard to know if this episode had an effect on National’s management, but they did buy new equipment for the amplifier lab. “We ended up with newer and better equipment, so it turned out to be a blessing,” Bob’s friend and analog guru Paul Grohe relates.

Another wild story comes to mind, the day when Bob got so exasperated at his computer he dropped it off the third-floor parking deck at National Semiconductor. He even arranged for friends to film the deed. Years later, when working on the Bob Pease show, the top management reminded Bob that National sold a lot of chips to computer vendors so he should not consider throwing any more computers off the parking deck. I could see the disappointment in Bob’s eyes. So I said, “Brian Halla never said we could not use a trebuchet to toss a computer up three stories to the parking deck.” I became concerned when Bob started doing the calculations to see how much energy we would need. We all explained that I was joking and we really should not be throwing computers anywhere, up or down.

When I told Bob Pease’s good friend, retired application engineer Marcello Salvatierra, the news about Bob, he wrote back with an epitaph more fitting than any random journalist could come up with.

  • What’s this RAP stuff anyhow?
  • I’m stunned and unable to comprehend. Something immeasurable has gone out of our lives. I will miss our dear friend RAP. He was such a knowledgeable person, not only about electronic design or semiconductor physics, but lots of other topics. From music to philosophy and, of course, his passion for the outdoors and the environment. He was well read and very unselfish, sharing all of his learning. I was witness to this when we were on seminar trips. He would spend time with customer problems until finding a positive result, no matter how trivial the question. On the road he would rather rent a car and drive to the next seminar location, taking the road less traveled so he would see the country. He would even videotape his meals, so he could enjoy it again later, he said. He lived life to its fullest every day. I learned a lot from RAP, not only electronic circuits or physics but about life itself. I’m grateful for the many years I was so fortunate to have known him. This is a sad day for the analog world.”

When i was designing my first major precision measurement system back in the golden years at NSC's analog devision. Bob warned me about Thompson and Seabeck effects on the measurement system accuracy. Thanks Bob.
I loved reading his articles and always looked forward to reading them.

I remember reading Bob's "What's all this Teledeltos Stuff Anyhow"? So one day I finally had to equalize the current flow through a high current three phase controller. One problem, I couldn't find Teledeltos paper anywhere. Then I had discovered Pasco Scientific sold field mapping paper, so I bought a bunch of it, all sizes. I had also figured out a way of substituting the expensive silver paint with much cheaper nickel based paint. I had sent Bob a picture of my updated PCB layout, showing how I modified the copper foil to equalize the currents to within 0.2%! I had sent him several dozens of sheets of the paper and he was real excited. I'm not sure if he ever used much of it though.
He and Jim will be deeply missed...

National has done a press release and has put up a remembering page with a video.
You'll have to search for them as I can't put links in the comments box.

Bob's dedication to the analog art is completely true in my experience...I interfaced with him several times over the last 25 years and he was always helpful...grumpy and direct, but always helpful. Six months ago...I was at a loss to solve a simple problem and I had no one else to talk to. Now, get this, I work for one of National's competitors! And, he was still willing to help me. Here's part of our interchange:
KLC: It's hard for me to believe there is a loading problem with 7mA, but it will be a few days before I can test this on a bench myself.

I looked through your troubleshooting book, but nothing caught my eye.
RAP: *** That may be because I only told how to Troubleshoot good designs?
KLC: The paper you wrote looks very interesting...I've read it quickly and will take a little more time with it tomorrow.

Yes, I believe my Tek scope will do an XY plot.
RAP: *** Well look at your Vout ( near + 750 mv) and put in 0 + 1 to - 7 ma through 1k. If the output moves - well, it shouldn't.

KLC: You're kind to make an effort to help me. How do people reward you for this dedication to your craft?
RAP: *** You can buy me a couple beers some day, if I can help you.
More later. / Beast regrds. / rap
Okay. Now we're never going to share that beer. I can't believe he's gone. This is a body blow.

Way back in 1990/91, I had submitted my first design idea to publication. It came back with red ink all over the page, and RAP signed at the bottom. The feedback was spot on, and improved my insight into my own circuit's behavior.

I am at a loss for words. Jim and Bob gone in less that two weeks. Not comprehensible.
I will miss them both. I hope someone will video the get together for us east coasters.
I am sure that we would all be there if we could.

This confluence of events is just too terrible for words. I have never me Bob personally, but he has always replied to my emails. He has always given me great advice. He will be missed.
