Won a global following and a five-year run on best-seller lists by fusing the genres of self-help and business literature in his 1989 book “The Seven Habits of Highly Effective People: Restoring the Character Ethic,” Mr. Covey was a Mormon, and some saw large elements of Mormon theology in his work, though his language was ecumenical. He denied any Mormon bias in his books, saying he drew inspiration from the Scriptures and from history’s great thinkers. In 1996, Time magazine named Mr. Covey one of the 25 most influential Americans, and Forbes called “Seven Habits” one of the top 10 business management books ever. As speaker of the House, Newt Gingrich drew on Mr. Covey’s advice and asked him to help write a chapter on personal strength in American culture. He entered the University of Utah at 16 and earned a degree in business administration. He spent two years in Britain as a Mormon missionary before returning to the United States to earn an M.B.A. from Harvard Business School. He sometimes preached the Mormon doctrine on Boston Common. At Brigham Young, he became an assistant to the university’s president and began teaching his self-help ideas on campus, drawing as many as 1,000 students in a single class. In 1983 he gambled everything he owned on starting the Covey Leadership Center, a training and consulting concern in Provo, Utah. In 1997 it merged with Franklin Quest, founded by Hyrum Smith, a time-management expert, to become the Franklin Covey Company. It now operates in more than 50 countries and had $160.8 million in sales last year. Mr. Covey is survived by his wife, the former Sandra Merrill; nine children; and more than 50 grandchildren.
