Robert Berger (mathematician)
- Robert Berger (mathematician)
Robert Berger invented the first aperiodic tiling using a set of 20,426 distinct tile shapes. This disproved a conjecture of Hao Wang (Berger's advisor), and was published as the "Undecidability of the domino problem" in the Memoirs of the AMS in 1966. This paper was essentially a reprint of Berger's 1964 dissertation at Harvard University; Berger's other two committee members were Patrick Carl Fischer and Marvin Minsky.
