Atlantic-Southwestern Broom Company

August Rosenberger got into the broom business by chance in the late 1800s. One of his customers, a farmer who was unable to make ends meet, asked Mr. Rosenberger if he would accept a small shack with one broom machine and one sewing machine in payment for his grocery bill. Mr. Rosenberger accepted and sent him on his way. By 1907, Rosenberger had a successful broom business and he set his sights on Baltimore.

Construction began on the Atlantic-Southwestern Broom Company in Baltimore in 1910. The business continued to grow and between 1922 and 1924, the building expanded with additional buildings to the east and north, adding 57,500 square feet of warehouse and space. Production peaked in 1932 at 3.6 million brooms and 300 employees.

The company closed in 1989. Harbor Enterprise Center opened it's doors in 1992 in the old Atlantic-Southwestern Broom Company and quickly became home to an eclectic mix of artists, woodworkers, and startup companies. Completed in early 2009, the ground floor has been converted to 20,000 square-feet of retail with office/studio space above. The factory is now home to more than fifty local businesses.
