Edward Simons apparently became the world’s oldest active conductor when he took up the baton at age 100 to conduct Samuel Barber’s Adagio for Strings on Sept. 10, during the “2017 Annual Concert for Remembrance, 9/11,” at Grace Episcopal Church in Nyack. Guinness World Records currently lists Spain’s Juan Garcés Queralt, who conducted a concert at age 99 and 311 days, as the oldest, but is reviewing an application to recognize Simons’ achievement.
