Jean and the author arrived in Nottingham in 1964 and met Professor Andrew and other staff members. After a short stay in the University Staff Club they found temporary accommodation in Beeston. In their search for accommodation, they noticed a building site in Chilwell on Clark’s Lane. They settled on number 7 where footings had just been installed. They moved in in March 1965. Jean found employment at the Rayleigh works in Nottingham. He started lecturing on aspects of aerodynamics. He was also setting up research facilities with his 1st student, Donald Ware, using a start- up grant from SRC. They soon had multi-pulse experiments running and tried observing 19F in a single crystal of calcium fluoride. By correctly orientating the crystal they found to their astonishment that the FID could be maintained for very long times compared with its normal T2 of 40 µ sec. His PhD supervisor, Jack Powles, was visiting at the time and when shown their new results thought he’d seen similar results in a pre-print recently sent to him. Their results were quickly written up and published in the new Journal, Physics Letters, a week or so after Waugh’s paper appeared in Phys Rev Letters, in 1966. Despite the fact that I, in his PhD thesis and with Jack in Phys. Lett, 1964, and Powles and Strange in a paper published in 1965, had published papers on solid echoes, Waugh claimed that he had discovered solid echoes. This led to internecine squabbling between the two groups over a four year period. Eventually, Ulrich Häberlen, one of Waugh’s team, returned to Germany where he set up his own group in Heidelberg. Shortly after in 1972 he was invited to spend a year working with Ulrich. In the meantime, at Nottingham, American post-doc, Allen Garroway, had joined his team and was keen to be involved with multi-pulse experiments. He quickly acclimatised himself with their new computer and wrote a program to perform a fast Fourier transform. Using this they were able to study 19F chemical shifts in a range of solids available from the Chemistry Department. When these were exhausted, Allen, Peter Grannell and the author sat in their Tea/Common Room considering what next to do. It was then that he suggested imposing a magnetic gradient on the specimen so that they could observe its spatial structure. Thus rudimentary imaging was born. Later in 1972, the author's wife, two children and the author set off by car to Heidelberg for a sabbatical year working with Ulrich Häberlen.
