I have divided this personal history into three phases; namely computer industry, computer-based systems and complex systems. While the years indicated are approximate and there is significant overlap, it provides a structure to conveying the essence of my career. I have worked with many talented people during my career and we have learned from each other. I thank them all and identify many of them. Further, I take the opportunity to provide some reflections that may have occurred during the experience or in several cases later in my career. I also provide a summary of what I consider to be my most important publications.
