Bobbie was a much more sociable person than I was, and several of my current friends in Canberra derive from her friendships. In the ANU and especially in the JCSMR, I met a very large number of people, many of whom became close friends. I also met a number of scientists during my overseas travels who became, and remain, close friends. Co-authorship of books was important in developing friendships. I will list some of them as Local Friends and Overseas Friends, arranged alphabetically.
