Bob Jenny was kind of an institution around here for many years. I first saw him back in the Dark Ages when I was a kid, on a local kid's show called 'Foreman Scotty'. Scotty was the foreman of the ranch, and one of the things he did at times was have Jenny on to talk about animals, primarily reptiles. Snakes, lizards, turtles, alligators. Over the years he did God knows how many programs for Scouts, schools, churches and anyone else who wanted the kids to learn about the critters.
He was a fine man, and was somewhere in his 70's(didn't catch the exact age when the news mentioned his death). He ran a nature center north of Oklahoma City, hopefully he had someone ready to take it over.
One instance I heard of was when he was out in the field with a Scout troop and one of the boys found a Gila monster. If you've never seen one, it's a truly ugly lizard, and one of only two venomous lizards in the world. Somehow in the pointing out and lecture the thing- slow moving most of the time, but can strike damn fast- managed to sink fangs into his hand. So he calmly detached it, put it back under a rock, and proceeded to give a demonstration of first aid for the bite of a poisonous reptile.
From what I understand, the kids were very impressed.
