Who invented a feather duster?

The first feather dusters were made of ostrich feathers, and were invented in Johannesburg, South Africa by Harry S. Beckner in 1903.

Actually if you want to know was the first one to ever create the feather duster- it was a woman. Her name was Susan Hibbard and is credited with the first Feather Duster Patent in 1876.

Her husband tried to take credit for what she had created, but she was known for what she did.

Feather Duster, 1876

Susan Hibbard's patent of the feather duster in 1876 was hard fought. In fact, it came down to her squaring off against her own husband, George Hibbard, in patent court before she was justly awarded ownership of the patent. It was not the first time a man had claimed a woman's invention for his own. Often times a woman, ignorant of patent law and schooled in subservience, willingly handed over their creation to a man. In other cases, ideas and inventions were stolen outright.

Susan Hibbard's notion of turning discarded turkey feathers into a duster may not rival the invention of the locomotive engine or the light bulb, but her fight for recognition went a long way in bolstering the spirits of other women inventors.
