Which of the following is correct:

1-With Planck, Bohr and Schrodinger, Einstein was one of the founding fathers of Quantum Mechanics.

2-Alongside Planck, Bohr and Schrodinger, Einstein was one of the founding fathers of Quantum Mechanics.

3-Alongisde with Planck, Bohr and Schrodinger, Einstein was one of the founding fathers of Quantum Mechanics.

4-Along with Planck, Bohr and Schrodinger, Einstein was one of the founding fathers of Quantum Mechanics.

I believe sentence 2 above is the best one. However, I also suggest:

Besides Planck, Bohr and Schrodinger, Einstein was one of the founding fathers of Quantum Mechanics.

or

Einstein, besides Planck, Bohr and Schrodinger, was one of the founding fathers of Quantum Mechanics.

The writer might consider the list complete with those individuals, but I can't assume that. (He doesn't mention Richard Feynman.)

Although R. Feynman bequeathed many invaluable contributions to Physics, he can't be said to be one of the founding fathers of Quantum Mechanics.

Among other contributions he developed an alternative mathematical approach to Quantum Mechanics, the path-integral formalism, but all the main ideas of Quantum Mechanics, as well the traditional approaches, were already ready.

In my view it is appropriate to say the R. Feynman was one of the founding fathers of

__Quantum Field Theory__.
