   Format: MarkdownItexReading through these, I realize that I had not actually appreciated before that the introduction of the EM-potential $A$ is very much already due to Maxwell himself (following Thomson). The *elimination* of $A$ from the original equations to yield those that now bear Maxwell's name is apparently ([p. 6](http://home.ustc.edu.cn/~lxsphys/2021-3-18/The%20conceptual%20origins%20of%20Maxwell's%20equations%20and%20gauge%20theory.pdf#page=6)) due to Heaviside and Hertz, about 30 years later.
