Jacob Hochbrucker (also spelled Jakob Hochprugger; 1673 – 28 May 1783) was an eighteenth-century harp maker and musician credited with the invention of the single-action pedal harp popularized in Europe between 1729 and 1750 by his descendants, and particularly by the Dauphine, Marie Antoinette, who performed on it after her arrival in Paris in 1770.
