Dear Diane, Nicola, Andrew, Stephanie, Douglas, and Jennifer, I am so sorry to hear of the passing of your beloved father. Prof. Ferguson was truly a gentleman and a great scholar. He was kind, generous, and supportive of many junior faculty colleagues at Fairleigh Dickinson University, including me when I first started at the University. I remember Prof. Ferguson proudly talked about Douglas working as a physicist in France. My colleagues and I will miss him dearly. Sincerely, Alfredo Tan Professor of Electrical Engineering Director of Gildart Haase School of Computer Sciences and Engineering Fairleigh Dickinson University
