BRIEF HISTORY DURING THE SNOW ERA (1813-58)
"There is a Brewery in Broad Street, near to the pump, and on perceiving that no brewer's men were registered as having died of cholera, I called on Mr. Huggins, the proprietor. He informed me that there were above seventy workmen employed in the brewery, and that none of them had suffered from cholera, -- at least in a severe form, -- only two having been indisposed, and that not seriously, at the time the disease prevailed. The men are allowed a certain quantity of malt liquor, and Mr. Huggins believes they do not drink water at all; and he is quite certain that the workmen never obtained water from the pump in the street. There is a deep well in the brewery, in addition to the New River water."
- Snow, John. Communication of Cholera, 1855, p. 42
The brewery was written about by John Snow in part 2 of his book, and is at the corner of New Street and Broad Street. His description provided further evidence that cholera was spread by water from the Broad Street pump, and not through the air as many believed. It is not shown on the 1859 map but is in K 14 just below "S. E" in Broad Street Edwards Street in the lower left of the quarter mile square.
While not named by Snow, the brewery was the Lion Brewery which existed on Broad Street from 1801 until it was demolished in 1937.
