The signed version of the following references, given to me for general purposes, were handed by me in 2002 to my research supervisor, Dr Jeff Hughes, of the Centre for the History of Science and Technology, and are held by the University of Manchester.

I have other references if requested.

Reference 1.
Ms. Helen Gavaghan researched and authored for us a book entitled "The History of EUMETSAT". EUMETSAT, the European Organisation for the Exploitation of Meteorological Satellites was formed in 1986 and has undergone major developments within the last 16 years.

The work carried out by Ms. Gavaghan was of a very high standard and the finished book is proof of her expertise. She diligently researched hundreds of official documents and obtained additional background information by conducting interviews with major players in satellite meteorology throughout Europe.

In the book she has very clearly and accurately documented not only the political nuances and technical challenges but also managed to capture some of the tensions and triumphs of the organisation's development to date.

I consider her to be highly professional and my editorial staff were able to work with her in a very constructive and effective teamwork environment.

In summary, I commend her expertise and dedication to the job of researching and authoring an excellent book dealing with complex technical and political issues.
Dr. Tillmann Mohr, former Director-General
EUMETSAT.

I found Ms Gavaghan energetic and very thorough in her research and interviews. She would give both Dr Weiffenbach and me drafts and we would correct them on scientific accuracy.

I always found that she followed up on my suggestions with respect to her learning and background and interviews of other people. I often could see in her rewrites evidence of correlations and connections which she made which we had not really thought about.

I most certainly recommend Ms Gavaghan as a writer and, to a significant extent, as an historian.
