A new principal was hired for the city's first Arabic-themed public school, the education department announced Tuesday, five months after the academy's founding principal said she was forced to resign. Holly Reichert, who graduated from Columbia University and has taught in the Middle East, was hired to lead the Khalil Gibran International Academy in Brooklyn, which opened last September with about 60 sixth-grade students. The school, named for the Lebanese Christian poet and peace advocate, emphasizes Arabic and Arab culture. Reichert, 42, replaces interim principal Danielle Salzberg. Salzberg, who is Jewish and doesn't speak Arabic, had replaced Debbie Almontaser, who stepped down in August over an interview she gave in which she discussed the word "intifada," an Arabic term commonly used to refer to the Palestinian uprising against Israel.
