Hermann Marcus was born in Germany in 1828. As a young man, before moving to New York in 1850, he gained experience at 'Ellemeyer', the court jewellers in Dresden. His first job in New York was at Tiffany & Co, though he soon moved to Black Ball & Co. In 1864 he started his own firm, a partnership with Theodore Starr, forming Starr and Marcus. Though highly successful, the firm was dissolved in 1877, Marcus returning to Tiffany. In 1884 Marcus left Tiffany to become a partner in the firm Jacques and Marcus where his son William was already a partner, and in 1892, when Georges Jacques retired, the firm became known as Marcus & Co. They exhibited at the 1900 Exposition Universelle in Paris, where they showed beautiful examples of flowers with plique-à-jour enamel. In 1962, after an illustrious career, they merged with Black Starr & Frost.
