I think you can include a number of others to your list, for
instance Steinmetz. I am not sure Sarnoff should be included among
inventors and scientists. He was something of a genius business man but
not a technical innovator. Also, which Collins, the one I think of is
A.Fredrick Collins, one of the early innovators of wireless. Also wrote
a pretty good early text book. Art Collins, of Collins Radio fame was
again an innovative business man rather than a technical innovator. He
hired the best engineers he could find for his business. I am not sure
Oliver Heaviside is quite so unknown but maybe so. He deserves better. I
tend to draw blanks on names but know there are a bunch of others.
Modern electrical distribution mostly originated with Westinghouse
(AC) although Edison probably deserves to get credit for the idea of
electrical distribution.

According to Mr. A.I. Google, the grounding of the neutral line became
mandatory with the 1913 update to the NEC.? Grounding of the building
service was not explicitly required until 1918.? It seems that the NEC
has always been a work in progress. My search terms were: "when did the
NEC require that the neutral line be grounded" and "when did NEC require
grounded outlets".
Tesla, Sarnoff, Armstrong, de Forest, Shockley, Collins, among many
others, are all demigods, some with a vocal cult following, others with
vocal detractors.? For me it would be Oliver Heaviside and John Costas
to name two relatively unknows but both have made great contributions in
the field of electrical engineering.
