Two others who come to mind are https://en.wikipedia.org/wiki/Charles_Proteus_Steinmetz https://en.wikipedia.org/wiki/Charles_Proteus_Steinmetz and https://en.wikipedia.org/wiki/Charles_F._Scott_(engineer) https://en.wikipedia.org/wiki/Charles_F._Scott_(engineer) Steinmetz contributed heavily to AC systems theory which helped understand and expand transmission. while Scott contributed a lot to transformer theory and design (I have to find his Transformer book.)
