Mozaffar ad-Din Shah Qajar
The slogan "Moser - the king of glass" originated in January 1869, when the director of the Vienna Museum for Art and Industry Rudolf Eitelberger issued a certificate about the perfection of Ludwig Moser's glass. Its quality was also confirmed by the medal from 1873 Vienna World's Fair. This year, Moser became an official supplier of glass to Vienna for the Austrian Imperial Court of Franz Joseph I. Since 1901 for the Persian Shah Mozaffar ad-Din Shah Qajar and from 1908 for King Edward VII of England. Later also for Pope Pius XI, the Turkish sultan Abdul Hamid II., and the king Luís I of Portugal and his wife, Maria Pia of Savoy. At that time, Moser already had a sales office in New York, London, Paris and St. Petersburg.
