Nov 17, 2016 at 9:33	comment	added	Ben McKay		I recall that Kaehler invented the notation $d$ for exterior derivative; Cartan had used $\omega'$ instead of $d\omega$. Pfaff realized that a line subbundle of the cotangent bundle, locally written as the zero locus of a 1-form $\omega$, has an invariant, which we can think of as $d\omega$ restricted to the hyperplane $\omega=0$, but defined only up to rescaling. So roughly, Pfaff knew about $d\omega$ for $1$-forms, but not quite. I know Poincare played some role in the story, as did Cartan, but I don't know exactly what.
