First American Women Inventors

Before the 1970s, the topic of women's history was largely ignored by the general public. Women have probably been inventing since the dawn of time without recognition. Many women faced prejudice and ridicule when they sought help from men to implement their ideas. Property laws also made it difficult for women to acquire patents for their inventions. By 1850 only thirty-two patents had been issued to women.

Sybilla Masters (1715)
Sybilla Masters invented a way to clean and refine the Indian corn that the colonists grew in early America and received the first patent issued to man or woman in recorded American history in 1715. Masters' innovation processed the corn into many different food and cloth products.


Catherine Greene

American Patriot

Businesswoman and Inventor of the Cotton Gin

Catherine Littlefield was born on February 17, 1755, on Block Island off the coast of Rhode Island. Her father, John Littlefield, served in the Rhode Island legislature, and her mother, Phebe Ray, was a descendant of the earliest settlers of Block Island. Her mother died when Catharine was ten years old, and she was sent to live with her aunt and uncle, Catharine Ray Greene and William Greene – the future governor of the state – in East Greenwich, Rhode Island.

Her aunt, an attractive energetic woman who was known as a charming hostess, took over the role of Catherine's mother, and supervised her education as a young woman of the upper classes. Present during her aunt's many social gatherings, Catherine caught the interest of several of their bachelor acquaintances when she came of age. A notable visitor was Benjamin Franklin, who had been a close friend of Aunt Catharine.
