In 1922 Robert Linzeler entered into a brief partnership with Alexander Marchak. Robert descended in family history from the renowned Linzeler jewelers who had been working in the trade since the early 19th century. Alexander was the son of Joseph Marchak who came to paris in 1918 (known as the Cartier of Kiev). Linzeler et Marchak was created and opened at 4 rue de la Paix in Paris in 1920. They worked with craftsmen and specialist workshops and exhibited at the 1925 Paris Exposition Internationale des Arts Décoratifs et Industriels Modernes. The partnership ended when it was said that the exhibition judges liked of Marchak’s contribution over Linzeler’s. This caused Alexander Marchak to take over the shop at 4 rue de la Paix. He kept the name Linzeler et Marchak until December 1927 when he changed it to A. Marchak. Robert Linzeler continued to run his business from the two other shops he owned on rue d’Argenson and rue de Turbigo.
