George Hunzinger was a furniture maker during the later half of the 19th century. He emigrated to the United States in 1855 and began manufacturing furniture in New York City. Like his contemporary furniture makers of the Victorian Age, Hunzinger's pieces are very decorative. What is unique about his furniture is the innovative and distinctive designs he patented. This site contains information and photo's of Hunzinger's work.
