Description (Brief):
Joseph Harrison, Jr. (1810-1874) was an American engineer who, in the 1840s, designed and built rolling stock and railroads for the Russian government. Returning home in 1852, he established the Harrison Safety Boiler Works in Philadelphia. The American Academy of Arts and Sciences awarded Harrison its 1871 Rumford Gold Medal for his safety improvements to steam boilers. This is the patent model for his Improved Steam-Boiler patented in 1859 (U.S. Patent 25,640).
