# Title: Holland Circle by Baumann and Kinzelbach


## Description: This intriguing item is almost certainly a Holland Circle by German scientific instrument makers Baumann & Kinzelbach. The Holland Circle, sometimes referred to as a Dutch Circle, was used in land surveying and is a precursor to the theodolite, an optical instrument for measuring angles. Baumann and Kinzelbach were based in Stuttgart, Germany, and in addition to crafting surveying instruments and compasses, also created a 2-foot tall "comet seeker" used at the Gotha Observatory near Gotha, Thuringia, Germany. Crafted from bronze with a handsome wooden stand and complete with its custom carrying case, this finely-calibrated instrument is a unique and elegant piece of scientific history. Engraved "Baumann & Kinzelbach Stuttgardt" Circa 1820 16 3/4” high x 8 1/8” wide x 8 1/8” deep Case: 7/8" high x 9 1/4" wide x 11 1/2" deep References: Gotha- the Instruments of the observatory, 1988, by G.
