The Seth Thomas Clock Company was founded in 1813 by renowned American clockmaker Seth Thomas (1785-1859) of Connecticut, USA, and pioneered the mass production of clocks. After Seth Thomas's death, his son, also Seth Thomas (1816-1888), continued operating the business. Their 'Adamantine' model was released in many variations. This particular model features two pillars on either side of the clockface, however other Adamantine variants could have none or up to three or four half-pillars on either side. This style of black mantle clock appears to be inspired by French clocks of the 1860s, which had gained popularity in the United States. While those clocks were often made with onyx, slate, or marble, Seth Thomas uses a durable celluloid veneer named Adamantine over a wood case to replicate the appearance of the original materials. This object is representative of the innovative manufacturing processes of pioneering clockmaker Seth Thomas and his company.
