Sybilla Masters Wikipedia
Sybilla Masters (died 23 August 1720), was an American inventor. Sybilla Masters was the first person to be given an English patent in America, and possibly the first inventor of her sex in America. She was given a patent for a corn mill in 1715 in her husband's name, as women were not allowed to have their own patents in that time and place.
Though not much is known of Masters' early life it is thought she was born in Bermuda as her father had emigrated there in 1687.
