In 1960 Bud Eldon was working for HP in Palo Alto - his son Tony and I were in Dick Empey's 4th grade class at Ohlones Elementary School which was at the time on Charleston Road.
One day, Bud brought an HP Oscilloscope, signal generator, and decade counter to our class to demonstrate the concepts of frequency and measurement. Each student in the class got to go up and adjust the frequency and watch the scope waveform change and read the output on the decade counter. I was fascinated, and decided at that time that HP would be a pretty good place to work.
I had one opportunity to reconnect with Bud at HP around 1974 when he was a lab manager at HP Santa Clara Division - I exercised the "open door policy" to go visit him and say "hi" even though I was "just" a summer student intern in one of the computer divisions. He was gracious as always, and remembered times I had been at their house.
Prayers and condolences to Betty, Tony, and the rest of the family.
