Freddy Hill is the somewhat pseudonymous identity of a guy born in Madrid, Spain in 1951, who, after a lifetime of world wandering has settled temporarily in Houston, Texas, USA. By profession I'm an electrical engineer, although by now I seem to have strayed away from my training as much as I have from my birthplace.
I have no particular area of expertise, but tend to be somewhat of a nitpicker. I think that this is not a bad trait in a would-be encyclopedist.
