C.S. Peirce was the grandfather of Codd’s relational database model.

"In computer science, the relational model for databases was developed with Peircean ideas in work of Edgar F. Codd, who was a doctoral student of Arthur W. Burks, a Peirce scholar.”

Good grief. Peirce is the Genghis Kahn of ideas: an absurd number of them have his genetics, can trace their lineage back to him.
