From serving in the Merchant Marine (1917 to 1922) and travelling to Hong Kong, Harold Tishler was first exposed to cloisonné enamels. From here his passion began. Tishler moved to Vienna to study with Josef Hoffmann and Michael Powolny. Experimenting with enamel techniques, he learned liquid enamel dipping from his friend Edward Winter. In 1937, he exhibited at the International Exposition in Paris, where he won gold and silver medals. That same year, his work was included in a silver exhibition at the Metropolitan Museum of Art.
