MARCUS AND CO 

Founded in New York in the 19th century by Herman Marcus, a German immigrant to New York who began his US career working at Tiffany & Co, and his sons William and George. An initial partnership with a George B. Jacques had the firm trading under the name Jacques & Marcus until 1892 when Jacques retired and the company began trading as Marcus & Co. Known as widely for their subtle, intricate and innovative techniques as for their use of exceptional gemstones, the Marcus triumvirate enjoyed huge success in a remarkably short period. Having successfully navigated the Depression, the onset of World War II and accompanying luxury taxes proved too much and the firm was sold to Gimbels in 1941 and it subsequently merged with Black, Starr & Frost in 1962.
