Heiner Marxen,
a German computer scientist and software engineer, M.Sc. in computer science from Technical University of Berlin in 1986, and author of Chest, a Program for Solving Orthodox Chess Problems [2].
Heiner is a well known Busy Beaver expert [3].
Additionally he introduced a method to compute Rook Paths Puzzles [4].
In 1973, he has written the first precursor of Chest, written in Fortran-II (no recursion) to solve mate-in-two problems [5].
It did not need or use any tapes and ran on an IBM-1130 with 32 K bytes, and took half an hour for one job [6].
