Albrecht Heeffer, a Belgian electrical engineer, philosopher and researcher with interests in the history of algebra, computational models for scientific discovery, recreational mathematics, and further in chess, computer chess and shogi. He holds a degree in electrical engineering and a Ph.D. in philosophy from Ghent University in 2006 on the topic of emergence of symbolic algebra during the sixteenth century, and is post-doctoral fellow of the Research Foundation Flanders (FWO) and member of the Center for Logic and Philosophy of Science at Ghent University. In 1984, during a three month visit of the Turing Institute in Glasgow, Albrecht Heeffer worked on automated acquisition on concepts for the description of middlegame positions in chess, supported by Donald Michie, John Roycroft, and Tim Niblett.

Albrecht Heeffer was member of the Bionic Impakt team with Hans Secelle, and provided the hardware, worked through the test sets, added the endgame databases and did some optimizations, while they later joined the Ant team around Tom Vijlbrief.
