In the dim and distant past, Pedro's list was this amazing resource for
biologists. Speak to anyone of my age, and they will remember this list; in
the early days of the web it was the best place to go, to find out where to
find your bioinformatics tools.
Pedro's list hasn't been updated since 1995. There are still copies of it
around which google will find for you if you want. It turns out that Pedro
was, in fact, Pedro Maldonado Coutinho who was a graduate student at the time.
A little more poking uncovers his thesis from 1996; this explains why he
stopped maintaining the list. A little more poking reveals very little. He
worked in France for a while but then disappeared from the web record. A later
google hit suggests he might not have left biology altogether — but it's hard
to tell for sure.
Pedro, early web pioneer, I salute you!
