Origin & History
Origins and dates here are approximate summaries. Many idioms have disputed or unknown origins, and not every date has been checked against a historical dictionary, so treat specific dates and stories as a starting point rather than a citation.
Playwright John Dennis supposedly had his thunder effect stolen by another production in 1710.
The story was told in the 18th century and still explains the idiom.
