Who was Fernando Pereira?

When I look at the file it shows me:
Some of the benchmarks are inspired on a benchmark suite developed at
ICOT for their SIM project, and other benchmark choices were
influenced by discussions with ICOT researchers on the relative
performance of SIM-I vs.  Prolog-20.
-- Fernando Pereira
But the file name has probably a typo:
samples/peirera.pl
Pay respect to the ancestors, and write their names correctly.
Its obviously nonsense, because the original name was:
These benchmarks are designed to identify
pereira.tar Fernando Pereira's benchmarks (26-DEC-86)
pereira.txt

These tests are a nice piece of history and
require some research to get the names right.
