Many of you will know that Sheldon Green died suddenly, towards the end of 1995. When Ewine asked me to say a few words at this meeting, in Sheldon's memory, I thought it very appropriate to do so and did not hesitate to agree. Although several people here probably knew Sheldon personally better than I (because our careers evolved on opposite sides of the Atlantic), it is possible that no-one present is more familiar with his published work.
