I had Ben as a graduate teaching assistant when I was an undergrad in Wildlife Science at TAMU. A very kind and gentle man. I have seen him a few times over the years as we went our separate ways. We joked about both the Prof who taught the course (Jim Teer) and how Ben didn't know a whole lot more about the subject matter (population dynamics) at that point than we did. He sure did fake it well though.
I'll miss his PM's about stuff, the latest being the new theory of tick fever from Texas cows killing huge numbers of buffalo. We both agreed that it was more than plausible.

God's speed Ben. Prayer's and best wishes for the family.
