It was the home of Garrett Morgan from 1904 to 1963.","why_significant":"The house is tied to Garrett Morgan (1877-1963), an inventor and businessman who lived here for nearly sixty years. He began his clothing manufacturing and hair refining businesses here, patented a safety helmet in 1912 and an electric traffic signal in 1923, and founded the Cleveland Call in 1920. The reviewer's comments indicate it appears to meet Criterion B.","narrative":"This modest two-story frame house at 5202 Harlem Avenue in Cleveland was the home of inventor and businessman Garrett Morgan from 1904 until his death in 1963. The building is a late nineteenth century vernacular structure, long in proportion to the width of its facade, with a gable roof of slate and a stone foundation. Its only notable feature is a later front porch with four round columns on a masonry base, and the original horizontal wood siding is now covered with imitation brick asphalt siding. Morgan worked with textile machinery and started a clothing manufacturing business here, along with the Morgan Hair Refining Company. He patented a safety helmet, an early gas mask, in 1912, and it was used in a dramatic rescue in 1916. He also invented an electric traffic signal in 1923 and founded the Cleveland Call in 1920, forerunner of the Call and Post. The house sits on an older residential street in the heart of a Black neighborhood, opposite a large clothing factory. It is listed as vacant.","period_of_significance":"1904-1963","architect_builder":null,"architectural_style":"Vernacular","criteria":["B"],"status_note":"Listed as vacant; interior in fair condition and exterior in poor condition.
