In recognition of his exceptional commitment to fostering broad appreciation for classical music, Boston Landmarks Orchestra conductor Charles Ansbacher was presented with the centennial medallion by Harvard Extension School Dean Michael Shinagel. The event was part of the Extension School’s centennial celebration. Held in Sanders Theatre, the Jan. 29 ceremony included an all-Beethoven concert performed by the Boston Landmarks Orchestra, featuring renowned pianist Andre-Michel Schub. (The event also marked the Boston Landmarks Orchestra’s 10th anniversary.)“The Extension School and the Boston Landmarks Orchestra share a mission of service to the community,” said Shinagel. “It is fitting that we honor maestro Ansbacher for his countless contributions to enrich the cultural lives of Bostonians, on the occasion when we celebrate 100 years of offering educational opportunities to the public.”To learn more about the Harvard Extension School’s centennial events, visit the Harvard Extension School Centennial Web site.
