although born in Wales in 1936, is one of the most influential figures in recent North American brewing education. Lewis graduated from the University of Birmingham in England in 1957, where he also earned his PhD in 1960. By 1962, he was hired at the University of California at Davis as a researcher and in 1964 he set up the brewing program and laboratory at UC Davis, where he stayed for more than 30 years. By the late 1970s, he began university extension classes where he brought previously unobtainable technical brewing knowledge to students needing less than a university degree. During his time as a professor, he brought the science and technology of malting and brewing to nearly 6,000 students from all over the world. In doing so, he allowed for the proliferation of technologically inclined microbreweries, advancements in all echelons of brewing, and widespread beer quality elevation. Through his efforts, UC Davis became one of the preeminent centers of brewing studies in North America. The university honored him with the Distinguished Teaching Award in 1989, and in 1995, Dr Lewis accepted Emeritus status, still continuing his extension and consulting endeavors. He is a prolific writer, researcher, and speaker and the author of Stout in 1995, Brewing in 2001, Essays in Brewing Science in 2006, and more than 100 technical papers. He is a Fellow of the IBD and has been honored with the MBAA Award of Merit and the IBS Recognition Award. Dr Lewis has always been a consummate ambassador and a tireless advocate for well-made beer. His dramatic speaking style, generosity, dry sense of humor, and occasionally nonconformist opinions have educated, challenged, and amused brewing students and professionals for more than a generation.
