Pascual Jordan was one of the founders of quantum mechanics. For instance Jordan algebras of quantum observables are named after him.
A brief biography of his scientific life is in the appendix of

Early discussion of quantum mechanics (and apparently introducing that term) and recognizing the matrices in Werner Heisenberg‘s matrix mechanics:

and with emphasis on the Born rule and quantum probability:
