American virtuoso violinist, recognized in Europe and the United States as one of the finest performers of her day.

Powell early displayed musical talent and took up the violin. Encouraged especially by her mother, an amateur musician and composer, she studied under teachers in Aurora, Illinois, and in Chicago. At age nine she made a six-week tour in Illinois, Wisconsin, and Michigan with the Chicago Ladies' Quartet. She was sent to Europe in 1880 to study music, working with Henry Schradieck in Leipzig, Germany, Charles Dancla at the Paris Conservatory, and Joseph Joachim (Joachim, Joseph) at the Royal High School of Music in Berlin.

In 1885 she made her formal concert debut with the Berlin Philharmonic and her American debut with the New York Philharmonic Society. For the next seven years Powell toured annually with the latter orchestra. In January 1889 she gave one of the earliest American performances of the difficult Tchaikovsky Violin Concerto. Her repertoire was broad and included much modern work. Her performance of works by Max Bruch (Bruch, Max), Jean Sibelius (Sibelius, Jean), Antonín Dvorák (Dvořák, Antonín), Édouard Lalo (Lalo, Édouard), and Camille Saint-Saëns (Saint-Saëns, Camille) helped introduce these composers to American audiences. In 1894 she organized the Maud Powell String Quartet, with which she toured for four years.

Powell's place in the first rank of contemporary violinists was evident from her popularity with generally more discerning audiences in Europe. British and European tours in 1898 and from 1900 to 1901 were highly successful. Powell also made extensive American tours (1901–02, 1903–04) and a South African tour (1905–06). Alternating American and European tours until 1910, she thereafter played largely in the United States.

Powell's technical accomplishments on the violin rested on a firm base of sensitive musicianship and understanding. She was also the first violinist recorded by the Victor Talking Machine Company. Powell died on tour in 1920.
