Little is known about the French clockmaker Raingo, who almost certainly apprenticed in Paris circa 1790. He moved to Belgium, circa 1800, probably for political reasons, and from the signatures on some of his clocks, it is known that he worked in Gand and Tournay. Later, in 1823, he is recorded as being clockmaker to the duc de Chartres. The company itself became Raingo Frères in 1825 and thereafter clocks bear their signature with various Paris addresses. The firm exhibited at many of the important exhibitions of the second half of the 19th century and was known for the fine quality of its ormolu.
