Abstract: Peter Hall left us about two year ago. His passing was an irreplaceable loss to the statistical community. I lost a long-time mentor, collaborator, and friend. In this article, I share with readers certain stages in my career during which Peter provided me much help, things that I learned from him about research and research attitude, our research collaborations, and more. I am only one of many statisticians who benefited from Peter's generosity in helping others, especially young researchers. My example demonstrates the importance and influence of Peter and his generosity on our growth and career development.

Key words and phrases: Collaboration, density deconvolution, fond memories, image processing, inverse problems, jump regression analysis, photography, steam trains.
