Dyson was a chemistry professor.


Nygma finds Dyson in his lab and holds him at gunpoint. Nygma gives him several riddles to solve, but Dyson is unable to answer any of them correctly. Nygma then ties him up and offers him one last chance to solve another riddle, but Dyson is once again unsuccessful. Unsatisfied with Dyson, Nygma ignites the lab with gas tanks and leaves, causing the lab to explode, killing Dyson in the process.[1]
