# Edison publicly campaigns against alternating-current distribution as deadly

Date: 1888

## The fact

From 1888 [Edison](/people/thomas-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. [Tesla](/people/nikola-tesla)’s work for Westinghouse is a related person, not this Fact.

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.

## Evidence and sources

IEEE/ETHW current-war summaries and Smithsonian Magazine’s documented account independently describe the 1888–90 campaign.

Official or archival record: Engineering and Technology History Wiki — Thomas Edison (https://ethw.org/Thomas_Alva_Edison; IEEE / ETHW).

## Significance

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.

## What is established and what is not

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.

What would change the picture: a contradictory original with a different date or name, or a measured series that can be argued, with lag and alternatives, as a consequence of this instrument rather than of later institutions.

The date is the date of this instrument, not a licence to back-date every later harm or benefit.
