Marvin was a lifelong ham. He was a physics major in college and always interested in technology. He was a professional pilot and my flight instructor for my glider and instrument ratings. He was a very patient teacher, and he could explain the why as well as the how. Marvin had many interests, including motorcycling, bicycling, kayaking, astronomy, and programming (he did the programming for several of the Henry Radio products). He was our flying, motorcycling, and hamfest buddy. He is sorely missed by all, and especially by Betsy, WB4ZYK.
