Ingeborg Rasmussen (1901-1988) was a Danish ceramicist. After working at the Royal Porcelain Manufactory from 1917 to 1924, she founded her own studio, RAS Keramik, with her husband, Jens Gaarde Thomsen. She created objects that were both functional and decorative, often characterized by colorful, hand-decorated patterns. Her ceramics were widely exhibited, including at the Milan Triennale in 1954, and her works are still sought after by collectors of Danish ceramics.
