Thomas Alva Edison was awarded more patents on inventions than any other American.
When he died in 1931, Americans wondered how they could best show their respect for him.
One suggestion was that the nation observe a minute or two of total blackout. All electric power
would be shut off in homes, streets, and factories. Perhaps his suggested plan made Americans
realize fully what Edison and his inventions mean to them. Electric power was too important to
the country. Shutting it off for even a short time would have led to complete confusion. A blackout
was out of the question.
On the day of Edison's funeral, many people silently dimmed their lights. In this way they honoured
the man who had done more than anyone else to put the great force of electricity at his countrymen's
fingertips.
