Christopher Hogwood, one of the leading figures in period-instruments and historcally informed orchestral performance, has died at 73.
Hogwood, a Cambridge University-educated

He served as artistic director of the Handel and Haydn Society of Boston (1986-2001) and music director of the St. Paul Chamber Orchestra (1988-92) and Mostly Mozart Festival of London’s Barbican Centre (1983-85). He also was principal guest conductor of the Basel Chamber Orchestra in Switzerland.
Hogwood held academic posts at Cambridge; the Royal Academy of Music; King’s College, London; Gresham College, London; and Harvard and Cornell universities in the U.S.
His activities as a musicologist included serving as chairman of the ongoing new edition of the complete works of Carl Philipp Emanuel Bach.
Hogwood was a prolific recording artist, once dubbed the “Karajan of early music.” Perhaps the best-known of his more than 200 recordings with the Academy of Ancient Music were their pioneering period-instruments cycle of the Mozart symphonies and acclaimed accounts of Handel’s “Messiah” and Vivaldi’s “The Four Seasons.” In later recordings with modern-instruments orchestras, he essayed modern repertory ranging from Stravinsky and Martinů to Barber and Copland.
