My husband, who wrote this book, and I were married in 1927. One of our first joint projects was leading a class of engaged couples at Belmont Methodist Church in Nashville, Tennessee. When I saw how much his gentle humor and rich store of wisdom meant to those young adults, I wanted many others to share what this husband of mine had to give. Furthermore, I was so impressed with the eagerness of young people to prepare themselves for marriage, that I shifted my own professional interests to this field. Ever since then we have been family folks in a double sense. We have shared a vigorously happy marriage and family life. And we have worked together side by side in family life education in our teaching, lecturing, and writing.It is with pleasure and some understandable pride that I introduce to you my husband and co-worker, your author, whom I hope you will enjoy almost (if not quite) as much as I do.~ EVELYN MILLIS DUVALL, PH.D.
