New York in 1876 — 37 Years Ago. The Brooklyn Bridge was then under construction — one of the supports can be seen on the New York side of the River.
New York in 1913. The growth of Dioxogen has been as wonderful as the development of this great city; it is now sold in every Drug Store in New York as well as in every other city and town in the United States. Dioxogen is used in over a million homes. It ought to be in yours.
Dioxogen was a product of the Oakland Chemical Company, which was first headquartered in Brooklyn, New York, and later moved its offices to Manhattan. Its factory was on Staten Island. The company began marketing a hydrogen peroxide solution as a medicine in the United States in 1881 as its principal product. Starting in 1901, they started selling the product under the brand name Dioxogen, until 1930, when the company disappears from the historical record. Today there is a company in Venezuela producing drugstore products such as deodorants and cleansers under the Dioxogen name, but it has no connection to the Oakland Chemical Company.
