Nolan Cool of Adirondack Architectural Heritage (AARCH) will present “Isaac Johnson: Stone Mason & Freedom Seeker.
”Master stone mason Isaac Johnson’s life story offers us a window into the African American experience in 19th-century Northern New York. Born enslaved in Kentucky and sold at age seven, Johnson eventually secured his freedom, served in a Black regiment of the Union Army during the Civil War, and afterward, made his way north to the St. Lawrence Valley. Working between rural Ontario, Ogdensburg, and Waddington, Johnson became a reputable stone mason and master builder. This presentation explores Johnson’s personal history, family life, and the architecture that his career produced.
