ABOUT AUTHOR
Jack H. Koehler
I am sixty-nine 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.
