Mel Tappan (1933 – 1980, born Melrose H. Tappan III) was the editor of the newsletter Personal Survival ("P.S.") Letter and the books Survival Guns and Tappan on Survival. Tappan was an influential leader of the Survivalist movement who advocated relocation to survival retreats in lightly populated regions.
After attending Stanford University, Tappan first worked as a banker in Texas. Tappan developed an ever-growing expertise in firearms while living in Los Angeles. He contacted Don Stephens after reading the "Personal Preparedness" columns by Stephens in Inflation Survival Letter. Tappan was invited to present a lecture as part of Stephens' "Seminars On Survival" (SOS) dinner series, giving him greater public presence and recognition. In the same time period, he collaborated with Roy Masters on writing and editing the book How to Conquer Negative Emotions (1975). He was also the editor of the 1977 book A Guide to Handmade Knives and The Official Directory of the Knifemakers Guild.
He then wrote a monthly column on survival topics titled "Survival Notes" for Guns & Ammo magazine. Shortly before his death, he also wrote a few monthly columns as the Survival Editor for Soldier of Fortune magazine. Through these publications and his 1977 book Survival Guns – which as of 2010 is still in print after more than 32 years – he became an influential spokesman of the "armed-defense" wing of the Survivalist movement. The back cover of Survival Guns quotes Laura Cunningham of The New York Times as describing Tappan as "The Survivalist voice of reason."
Tappan published what is perhaps the most important newsletter on survivalism and survivalist retreats in the 1970s, the Personal Survival ("P.S.") Letter. It was published from 1977-1982. The newsletter included columns from Tappan himself as well from Jeff Cooper, Al J. Venter, Bill Pier, Bruce D. Clayton, Rick L. Fines (aka "Ross Lee"), Nancy Mack Tappan, J.B. Wood, Dr. Carl Kirsch, Charles Avery, Karl Hess, Eugene A. Barron, Janet Groene, Dean Ing, Alexander Jason, James McKeever, Kurt Saxon, Bob Taylor, Reginald Bretnor, C.G. Cobb, Carl E. Krupp, and several other writers, some under pen names (such as "Dr. J.M. Browning"). The majority of this newsletter revolved around selecting, constructing and logistically equipping survival retreats. Following Tappan's death in 1980, Nancy Tappan took over the newsletter, renaming it Survival Tomorrow in 1983. In 1987 Carl E. Krupp became the new editor and publisher. The more recent survivalist author James Wesley Rawles credits Personal Survival Letter and Tappan's books as the primary influences in the development of his survivalist philosophy as well as the impetus for launching SurvivalBlog.com.
