GCHQ Farewell Book
F.J. Bentley OBE, GCHQ (1951-1968)

This red booklet is a so-called farewell book presented to F.J. Bentley OBE in 1968 on his re­ti­re­ment from the Government Communications Headquarters (GCHQ) in Cheltenham (UK). He re­cei­ved the farewell book together with a clock made by Elliott in London (UK). The book is unique in that it contains signatures of GCHQ personnel, including several well-known WWII codebreakers.

At present, we have no idea who F.J. Bentley was, but he or she entered service with GCHQ in 1951 — six years after the end of World War II (WWII). Although at some point Bentley was appointed Officer of the Order of the British Empire (OBE), his/her name cannot be found in the OBE data­base of the London Gazette. This is not unusual for intelligence service personnel however.

The clock was a regular gift to a retirement can­di­date. It has serial number 5458 EK and was manufactured in June 1966, roughly two years before it was presented as a gift to Bentley. 1
  

The farewell book is really something special, as it is highly unusual (and probably unwanted) that names and signatures of intelligence service personnel end up in the hands of the public. We will therefore not disclose all the names and signatures in the book, but only the names of people that are already publicly known and that have long since left GCHQ. It should be noted that the book is not signed by all GCHQ personnel, but rather by a subset from several departments.

The book consists of 22 pages that are sewed together. It is likely that the individual pages were each sent to one of the departments at GCHQ, where they were signed by the people that knew or had worked with F.J. Bentley.

Upon return of the signed pages, they were sewed together and bound in a carton cover with bright red lining, imprinted in gold with the text:

F.J. Bentley O.B.E.
G.C.H.Q.
1951-1968
  

Among the signatures, some of which are visible in the image above, are several famous names, such as Hugh Alexander [4], Shaun Wylie [5], Leslie Yoxall [6], Alan Rogers and H.C. Ricketts, all of whom had worked at Bletchley Park during WWII. Their shared background sug­gests that they worked for a de­part­ment within GCHQ that formed a bridge between WWII and Cold War crypt­analysis. Also on this page is Denis V. Mardle, who became a key mathematician at GCHQ.

The authenticity of the signatures in the book has been confirmed by a former GCHQ employee [2]. A similar farwell book is on public display in the GCHQ exhibition at Bletchley Park [3].

The overall condition of the book is very good, especially considering its age. There are various stains on the front and rear cover, resulting from spilled liquid, e.g. by putting a wet glass on top of it. The liquid has caused the otherwise bright red die, to appear washed out in some areas. The quality of the individual pages is excellent and no fading of the signatures is visible.
  

  1. The clockwork itself has serial number A9702.

Number of signatures per page
Below is an overview of the number of signatures on each of the 22 pages. Note that the names of many signatures are unreadable. Furthermore, we have chosen not to disclose the names of people that are not publicly known. The names of Hugh Alexander and Shaun Wylie appear on page 5 of the book, together with other people with a Bletchley Park background.
