We were [initially] entirely in Heisenberg's footsteps.
He had the idea that one should take matrices,
although he did not know that his dynamical quantities were matrices....
And when one had such a programme of formulating everything
in matrix language, it takes some effort to get rid of matrices.
Though it seemed quite natural for me to represent perturbation theory in the
algebraic way, this was not a particularly new way.

I guess the pioneers in quantum theory have more representation on the web than
most pure mathematicians.
