Green Mercury Barometer

Description
Nicolas Fortin, an instrument maker in Paris in the early nineteenth century, introduced a mercury barometer with a glass and leather cistern so designed that the barometer could be safely moved from one place to another. James Green began making Fortin-type barometers for the Smithsonian in the 1850s, though with a slightly different design to the cistern. This example marked “HENRY J. GREEN B'KLYN, N.Y.” was made after 1890 James Green's nephew and successor moved to Brooklyn.

I am very possibly the last living employee of Henry J. Green Instrument Company, which was founded in 1832 by James Green. As a teenager in the mid sixties I worked at their plant in Westbury, N.Y. They had moved from Brooklyn in 1959. My father was the general manager. I even knew one of the owners, who's last name was Weygand.. I understand he was a part owner in 1912. I packed hundreds of rain gages that were destined for the Kansas City depot. I filled up many a tube of mercury for the Fortin type barometers. Today, I own my own company, which is a manufacturing job shop. I actually continue the tradition of making weather instruments. I make the Adirondack snow density gage, which HJ Green used to make. My company's name is Gamma Instruments. I had a detailed history of the company as well as mid sixties catalogs. I have been looking for them for years. Hopefully, they will turn up one day.
