He was credited for improving the fire extinguisher in 1872, about 150 years after it had been invented in England.
What he actually invented was a type of fire standpipe and sprinkler in which water pressure from a reservoir and pump pushes water up and into a building to a valve that can be opened to make the water spray out of nozzles. That is nothing like what we call a "portable fire extinguisher" today.
