John Davidson was widely recognized as the founding father of fluidization in chemical engineering. He was a great thinker and had a tremendous ability to distill complicated problems into much simpler concepts. Much of his thinking was set out, along with that of his coauthor David Harrison, in their book , first published in 1963, a book that is still used today. John was still coming into his office in Cambridge until the very last weeks of his life, where he continued to work with final-year undergraduates and graduate students. Fluidization, and two-phase flows, continued to fascinate him, and that enthusiasm was transmitted to those around him. The following article was the last work that he wrote and was very much a reflection on his life and career. John passed away on Christmas Day 2019, with the article in its final stages of preparation.
