When we think of famous [female inventors](https://nygal.com/8-of-the-little-known-female-inventors-of-all-time/), we often associate them with men. But there are a number of women who have blazed new trails in science and technology. Some of the most notable examples of such women are Ada Lovelace, Hannah Slater, Tabitha Babbitt, and Ann Kiessling. In this article, we will explore the careers of these remarkable women. Ada Lovelace Ada Lovelace was born in 1819 in the English city of London. Her parents divorced shortly after she was born. Her maternal grandmother, Lady Byron, taught her science, literature, philosophy, and mathematics. She was tutored in these subjects from age four. Later, she met Charles Babbage, who later served as her mentor. She also studied advanced mathematics under Augustus de Morgan. Although Ada Lovelace suffered from sexism during her life, history has recognized her contribution in the field of science and technology. Her mother had a diverse education and helped her overcome challenges. She was also taught by Mary Somerville, who was an outstanding tutor. Lovelace credited her tutor with being her inspiration and reference during her career. Hannah Slater Famous female inventors include Hannah Slater, Mary Seacole, and Elizabeth Cady Stanton. Each of these individuals created products with unique skills and attributes. In the case of Hannah Slater, her innovation was a new technique for producing sewing thread from cotton. She was probably inspired by the methods used by her husband, Samuel Slater, to produce the thread at his mills in Derbyshire, England. Hannah Slater received a patent for her invention in 1773. The patent was later granted to her husband and Samuel Slater. The Slaters began manufacturing thread together and soon expanded their business operations into New Hampshire, Connecticut, and Massachusetts. Since the early 1700s, women have been creating products that help people live a better life. The first woman to receive a patent was Hannah Slater, who invented cotton sewing thread. Others, like Hazel Irwin, patented the cheese-press in 1808. While women have made progress in the past century, they remain under-represented in STEM fields. Tabitha Babbitt While men may make strides in the field of science and engineering, women have long made important contributions in product development and invention. One such female inventor, Tabitha Babbitt, was a member of the Shaker community in Harvard, Massachusetts, during the 18th century. This religious group was known for its frugality and furniture-making skills, and they held to the ideal of equality between men and women. Many of the earliest patented products were made by women. While men are typically the pioneers in a field like dentistry, female inventors have contributed to various technologies. For example, Shaker-Sister Tabitha Babbitt was responsible for the development of the circular saw, and her breakthrough in the field of false teeth was made possible by her development of a new technique. Ann Kiessling Ann Kiessling is an American stem cell researcher. She discovered the activity of a gene called reverse transcriptase in normal human cells. The enzyme was previously thought to only be present in retroviruses. Her work led to advances in IVF. She has also written many scientific papers. After submitting a prototype of her invention, she received positive feedback. She decided to pursue her idea further. She later founded a company with her father. El Dorado Jones El Dorado Jones was an American inventor who invented many things, including the travel size iron board and the light-weight electric iron. She also developed a muffler for airplanes, which she patented in 1923. Eldorado Jones was known as the "Iron Woman," and her factory employed only women. Her company's success made her famous, but she also faced a lot of opposition, which kept her from capitalizing on her successes. El Dorado Jones earned the nickname "Iron Woman" after founding a metalworking factory that only employed women over 40. Her inventions were revolutionary, and her most famous invention was an airplane muffler. Eldorado developed a prototype of an airplane muffler and tested it at Roosevelt Field. In 1919, she applied for a patent for the design and received it the following year.
