**7. Dedication**

This chapter is dedicated to the memory of *Leslie James Park Dun*can (\*Sumatra, 1922 + Scotland 2005), unforgetable diabetologist who created a centre of excellence at the Royal Infirmary of Edinburgh [42, 136–140], for his empathy with patients, students and colleagues, as it was recognized by one of the authors of this Chapter in the course of his postgraduate training in Edinburgh in 1980.
