History
- To simplify the complex calculations of manually adjustable nozzles, Clyde McMillan the founder of Task Force Tips on a napkin invented the automatic nozzle on May 10, 1968.
- Interestingly, although the NFPA had, in 1964, ordered NFPA 1964 that all automatic nozzles must maintain flow rates within fifteen GPM of their nominal value (most commonly 100 PSI), many firefighters mistakenly continue to use stream shape instead of the recoil felt during operation to judge fog nozzles' flow rate.

Famous quotes containing the word history:
“It’s not the sentiments of men which make history but their actions.”
—Norman Mailer (b. 1923)
“Tell me of the height of the mountains of the moon, or of the diameter of space, and I may believe you, but of the secret history of the Almighty, and I shall pronounce thee mad.”
—Henry David Thoreau (1817–1862)
“In history the great moment is, when the savage is just ceasing to be a savage, with all his hairy Pelasgic strength directed on his opening sense of beauty;—and you have Pericles and Phidias,—and not yet passed over into the Corinthian civility. Everything good in nature and in the world is in that moment of transition, when the swarthy juices still flow plentifully from nature, but their astrigency or acridity is got out by ethics and humanity.”
—Ralph Waldo Emerson (1803–1882)
