Edison publicly campaigns against alternating-current distribution as deadly
From 1888 Edison and associates publicly argued that Westinghouse’s alternating current was uniquely lethal, including through staged electrocutions of animals and through association with the electric chair. In the causal graph this event weakens Political Polarization, a driver that weakens Having a say in government — an improving welfare path.
Read the full account
From 1888 Edison and associates publicly argued that Westinghouse’s alternating current was uniquely lethal, including through staged electrocutions of animals and through association with the electric chair. The campaign is a dated publicity instrument.
Context
AC could travel farther at higher voltage. Edison’s DC stations had a short radius. Technical rivalry became a safety scare.
Thomas Edison is not the sole author of every later object, law, or museum label that uses the name. Shared work with courts, excavators, printers, spouses, officials, and later states does not erase a documented role, and it does not make an ancient person the signer of a twentieth-century statute.
Why it matters
Polarisation path around an energy standard. High confidence that the campaign occurred; medium on how much it delayed AC adoption.
A safety claim can be both commercially motivated and partly true. Store the campaign, not a cartoon of murder.

He authorised and voiced the anti-AC publicity. Harold Brown and others performed public animal electrocutions with AC.

What the sources establish
IEEE/ETHW current-war summaries and Smithsonian Magazine’s documented account independently describe the 1888–90 campaign.
Established: Edison-aligned anti-AC publicity including animal demonstrations from 1888. Not established: that AC was in fact more lethal in ordinary distribution, or that Edison personally threw every switch.
