October 5, 1856: The Union School, later renamed Ann Arbor High School opens the corner of State Street and Huron. There were eight teachers including Principal Theophilus Abbott.
Students could study either English or the Classics and special attention was given to those who wanted to teach. Most of those who entered the high school went on to college. In 1904 Ann Arbor High School was destroyed by fire.During the next two years, classes met in churches and rented office space in the area (the first portable classrooms). This building still exists in June of 2005. Known as the Frieze Building, it belongs the University of Michigan. The University is planning to tear it down and put a new dormitory complex on the site.
I'm not sure if this bell was used as a fundraiser to rebuild the school, was possibly used in the new school, or something else.
