Carl Halier (1873-1948) was a Danish ceramic artist and designer known for his innovative approach to ceramics and his collaboration with the Royal Copenhagen porcelain factory.

Halier was born in Copenhagen, Denmark in 1873. He began his artistic training at the Royal Danish Academy of Fine Arts, where he studied under the renowned Danish sculptor Vilhelm Bissen. After completing his studies in 1896, Halier travelled to Paris to further his training, where he was exposed to the work of contemporary French ceramic artists such as Ernest Chaplet and Auguste Delaherche.

In 1898, Halier returned to Denmark and established his own ceramic studio in Copenhagen, where he began to experiment with new forms and techniques in ceramics. His work was characterized by a strong emphasis on the form and function of objects, as well as a keen attention to detail and craftsmanship.

In 1904, Halier was appointed artistic director of the Royal Copenhagen porcelain factory, where he worked for more than thirty years. During his tenure at the factory, Halier was instrumental in introducing new forms and glazes to the company's product line, and he collaborated with a number of other prominent Danish designers, including Axel Salto and Svend Hammershøi.

Halier's work at the Royal Copenhagen factory was highly influential in the development of Danish modernism, and his designs are now considered among the most important examples of Danish ceramics from the early 20th century. His work was also exhibited internationally, including at the Exposition Universelle in Paris in 1900, where he won a gold medal for his designs.

In addition to his work in ceramics, Halier was also an accomplished painter and sculptor, and his works are held in the collections of a number of major museums, including the National Museum of Denmark and the Victoria and Albert Museum in London.

Carl Halier died in Copenhagen in 1948, leaving behind a legacy as one of Denmark's most important ceramic artists and designers.
