Description
The War Department Signal Corps transferred this aneroid barograph to the Smithsonian in 1923. One metal tag reads "BAROGRAPH / TYPE ML3 / SERIAL 102 / SIGNAL CORPS / U.S. ARMY / ORDER 110488 / DATE 5.22.23." Another reads "JULIEN P. FRIEZ & SONS.”
Julien P. Friez (1850-1916) was born in France and emigrated to the U.S. around 1868. He opened a machine shop in Baltimore in 1890 and was soon specializing in meteorological instruments. The firm began trading as Julien P. Friez & Son in 1913, and as Julien P. Friez & Sons in 1914.
