According to that paper, Nanson invented both.  I gather the later one
was invented with Baldwin.

I've now added what the paper calls Nanson to my web site, under the
name of Nanson (original).  It passes Smith and reversal symmetry, but
fails independence of clones and monotonicity.

In an attempt to reduce confusion, I've renamed the Nanson-Baldwin
method, which I used to call Nanson, to Borda-Elimination on my site. 
I give Baldwin as another possible name, though.
