This special issue of the Journal of Aeroacoustics is presented in honor of Prof. Stewart Glegg, and his many professional accomplishments. The enthusiasm of the many contributors to this volume, representing just a small subset of those who have benefitted from his work and collaboration, is just one indication of Stewart’s phenomenal impact. This article is an attempt to summarize Stewart’s personal and professional biography to date. His contributions to the aeroacoustics community include insightful technical advances in a surprisingly broad set of areas, extensive service particularly through his university and AIAA, and the inspiration, mentoring and advancement of many students and colleagues.
