I met Ken Eldred at Wyle Laboratories in Alabama in 1963 as a young, green engineer shortly after he formed a staff to support NASA's Apollo program. Later, I was joined by other graduates of the Institute for Sound and Vibration Research, Southampton University, England. Ken led us as we undertook exciting and challenging projects. At Wyle, Ken actively mentored us, encouraging us to develop our investigative skills, adapt to new technologies, and write understandable, readable, and useful reports. He encouraged me to produce ideas and he listened to my suggestions, which he carefully reviewed and then, gently, offered corrections and suggested direction. I, and many of us, owe our successful careers to his mentoring. I will describe some particular work and list some who prospered under his leadership. I moved back to England but then, later, returned to the United States and rejoined Ken at Bolt Beranek and Newman in Cambridge. Again he showed interest and encouragement as I expanded my noise work to other aspects of industrial hygiene, later forming my own companies.
