Grant Mill began life in the mid-19th century as a textile mill. The current complex was built around World War I by textile moguls B.B. & R. Knight, whose flagship brand was “Fruit of the Loom.” By 1935, jewelry firm Blacher Brothers was manufacturing here. The Blacher brothers were sons of Russian Jewish coppersmith David Blacher, who arrived in Providence with his family in 1900. Today Grant Mill has been repurposed into condominiums, a crucial form of adaptive reuse for a city burdened with vacant industrial space.
