[time-nuts] Part 2: Atomic Clocks: It is important that they keep good time.

[Rice, Hugh (IPH Writing Systems)]

Hi Tom,
The picture I attached was from the 5061B sales brochure, and probably taken in 1986.
I recognize the guy in the photo, I think he was a marketing engineer, but I can't remember his name.

Hugh,

What year is your photo from? Here's a similar, but older photo of hp's house standard:

This was from roughly 1966 (note the dual hp 5060A). The HPJ issue containing that article is here:

The house standard is featured on page 20, but there's also a glimpse of it on the top of page 15.

HP's Santa Clara Division (SCD), in addition to building the Cesium Beam Frequency Standard Atomic Clocks, was an official time-keeper for the U.S. Naval Observatory, maintaining the west coast reference for Coordinated Universal Time. This was done in our standards lab where we kept a rack of several HP Cesium standards. Hopefully the attached picture of the lab comes through for some of you.
