Very little is known of Florence Parpart, other than census records and United States Government patent applications. Born in the Hoboken, New Jersey, Parpart was listed as a housewife in the United States Census for the majority of her life. As is the case with many early female inventors, local sources paint an entirely different picture.
Although the first street sweeper patent was awarded to Eureka Frazer Brown in 1879, Parpart improved the street sweeper and its manufacturing process for widespread use. Parpart spent the majority of her life in New York City and Philadelphia, and both cities needed additional street sweepers to keep residential and commercial areas clean. Parpart won her patent in 1900.
