I have long been active in and supportive of conservation and historical preservation causes.

It was a country . . . that he and his people had known how to use and abuse, but not how to preserve.

I have taught history on the high school and college levels, and am or have been a lecturer at the Smithsonian, The National Institutes of Health, and numerous colleges and universities, mostly on science fiction and technology subjects.

I am also a Kentucky Colonel and an Honorary Mayor of Baton Rouge, Louisiana, among other things.

I write novels and other things.

I do not read SF as much as I used to. It's too much like a busman's holiday.
