Mildred Dilling (February 23, 1894 – December 30, 1982) was an American harpist. She studied under Henriette Renié in Paris. She first started performing in 1911, and traveled over 30,000 miles (48,000 km) per year at her busiest. She performed with many notable vocalists, had her own weekly NBC radio show, and appeared on the Bing Crosby radio show. She toured Europe and Asia multiple times, and often performed internationally. She enthusiastically championed the harp and gave many celebrities their first harp lesson, including Harpo Marx. In 1962 she helped found the American Harp Society. She devised a lever system for a non-pedal harp that made it more portable than a pedal harp but which allowed flexibility in harp tuning. Her extensive harp collection is held partially by Indiana University, and harp students still use two of her harp music compilations.
