FYI: The main interview (about 50 pages) with David Allan is a really
good read:
https://ethw.org/Oral-History:David_W._Allan
The set of 5 PDF addenda (~2 pages each) to the main interview are:
"Technical Background on the Fundamental Noise Problem"
https://ethw.org/w/images/e/e5/Allan_OH_-_FundamentalNoiseProblem.pdf
"The Development of MVAR and TVAR"
https://ethw.org/w/images/5/5f/Allan_OH_-_MVAR_TVAR_and_OptimumPrediction.pdf
"Perspectives on the Development of Commercial Cesium Beam Clocks"
https://ethw.org/w/images/0/02/Allan_OH_-_CommercialCesiumClockDevelopment.pdf
"Dave's Story on how GPS helped NASA/JPL synchronize their Deep Space
Network tracking stations"
https://ethw.org/w/images/a/ac/Allan_OH_-_GPSandtheDeepSpaceNetwork.pdf
"Sound of Music Experience in Italy (1969)"
https://ethw.org/w/images/b/b3/Allan_OH_-_MoreTravelStories.pdf
In general, the Engineering and Technology History Wiki (ETHW) is a
fantastic historical resource.

Hi,
I found this little text that may be an amusing read on how ADEV and
MDEV came to be among other things.
https://ethw.org/w/images/5/5f/Allan_OH_-_MVAR_TVAR_and_OptimumPrediction.pdf
The Lighthill book is very important little thing, which few seems to
know. It works on Fourier transform quite differently than any
other book on Fourier transforms I've seen. It is not meant as a strict
book, but a book to help students on their way, and it did help Jim and
Dave in their studies for sure.
Similarly the Snyder pre-cursor to MDEV seems to be read by few. It
provides the necessary sqrt(N) improvement as achieved with overlapping
frequency estimations.
Cheers,
Magnus
