At Sylvia Richardson’s career celebration last Friday, I gave a talk on How many components in a mixture? which was most relevant given Sylvia’s contributions to mixture inference over the years, including her highly influential 1997 Read Paper with Peter Green. The other talks highlighted the many facets of Sylvia to the field and the profession, including obviously her MRC Unit directorship but also her RSS Presidency when she drove along with Chris Holmes the remarkable society’s response to the COVID pandemic. The day ended up with a diner in Emmanuel College (in the Dining Hall rather than the larger, noisier, and more formal Hall where I was once invited for the Midsummer Dinner by Sylvia). It was also a great opportunity to reconnect with friends I had not seen for ages.
