This paper is a memoir of/for Daryl. A "memoir" is an historical account or biography written from personal knowledge. It provides my personal account of Daryl, the man, the physical educator, the intellectual, the teacher, and the scholar. In this account I trace Daryl's work from when I first met him in 1981 and the major conceptual ideas that drove his research and scholarship. I discuss his commitment to behaviour analysis, his integrity and his politics. I try to convey the ways in which he thought about research and the world more generally. I also give an insight into Daryl the advisor and, in particular, what he meant for his international PhD students and how, through them, his influence spread across many countries of the world.
