ABOUT AUTHOR
Jack H. Koehler
I am seventy three years old  and have had a passion for slingshots all my life.
When I was a kid, I was rarely without my trusty slingshot. Whether I was sent out
to bring the cows home for evening milking or going over to the neighbors for a
dozen eggs, I always had my beloved slingshot with me. I couldn’t walk in the
woods without scanning the trees looking for a suitable fork to make yet another
slingshot (I find myself still doing that). I couldn’t walk down a road without
constantly scanning for round stones suitable for ammunition (all the local roads
were gravel at that time).
I love the shooting sports. I have several rifles, shotguns, and pistols but rarely do I
ever shoot any of them. My slingshots are another story; I now practice target
shooting, with my slingshots, at every opportunity. During the middle part of my
life I went many years without shooting a slingshot because of other interest
(pocket billiards) and obligations. Looking back, I regret not making room in my
life for slingshot shooting during that period.
By profession I was a Hydrologist. I spent my entire career working for the U.S.
Geological Survey. During that time I authored twenty-five Professional Papers.
After retiring, I wrote three very successful books on pocket billiards.
