As the town celebrates the history of its former Highland School, which now houses Reading’s public library, longtime resident Peggy White is scheduled to tell the story of the building’s architect, Horace G. Wadlin, during a presentation scheduled for 7 p.m. Feb. 26 in the library, 64 Middlesex Ave. White has done extensive research on Wadlin, whose 19th-century architectural work includes several homes and buildings listed on the National Register of Historic Places, such as the Highland School and the Bowser Gazebo on Linden Street. Seats are limited. The program is free, thanks to the support of the Friends of the Reading Public Library. It is part of the “LiveWires — Lifelong Learning in the Library” series.
