Living Women Inventors

Here are some living women inventors whose ideas produced products used by NASA, home owners, computer companies and in many other fields.

Sally Fox
• Year of birth: 1955
• Birthplace: Menlo Park, California
• Occupation: Inventor/businesswoman/entomologist
• Invention: Inventor of commercially viable fiber-colored cotton.
Colored cotton had been grown for thousands of years but was not suitable for modern textile machines and had to be spun by hand. While working as a pollinator for a farmer seeking more pest-resistant cotton, Fox began breeding brown and green cotton. It took her eight years to develop plants that were uniform in color and size as well as commercially viable. Because it doesn’t need to be dyed, colored cotton needs minimal processing and is more environmentally friendly.

Temple Grandin
• Year of birth: 1947
• Birthplace: Boston, Massachusetts
• Occupation: Inventor/teacher
• Invention: Animal-handling devices
She has designed animal restraint systems that rely on behavioral principles rather than the use of force. Grandin studied how cattle react to ranchers and various stimuli, and designed stockyards and chutes that reduce stress and injury. Today, almost half the cattle in North America are handled or slaughtered using equipment designed by her.

Joy Mangano
• Year of birth: 1956
• Birthplace: East Meadow, New York
• Occupation: Businesswoman
• Invention: Self-wringing Miracle Mop
Joy Mangano invented the self-wringing Miracle Mop and made it a best seller on shopping channel QVC in 1992. She went on to develop numerous consumer products and sold her business, Ingenious Designs, to the Home Shopping Network (HSN) in 1999. She holds more than 100 patents and trademarks and has been successful as a businesswoman and engrepreneur.

Valerie Thomas
• Year of birth: 1942
• Birthplace: Maryland
• Occupation: Scientist
• Invention: Illusion transmitter
Valerie Thomas invented the illusion transmitter, which uses concave mirrors to create optical illusion images. After majoring in physics at Morgan State University, Thomas began her career at NASA. When she worked on Landsat, the first satellite to transmit images from outer space, saw the need for a technology that would deliver three-dimensional images. The illusion transmitter was patented in 1980 and is still used by NASA today. Scientists are seeking to incorporate it into technology that will give surgeons three-dimensional views of the human body.

Olga D. González-Sanabria
• Year of birth: N/A
• Birthplace: Patillas, Puerto Rico
• Occupation: Scientist/inventor
• Invention: Long-life nickel hydrogen batteries
Olga González-Sanabria played a key role in the development of the long-life nickel hydrogen battery, used to power the International Space Station. A native of Puerto Rico, she joined NASA’s Glenn Research Center in Cleveland in 1979 and has held a number of senior positions there.

Janet Emerson Bashen
• Year of birth: 1957
• Birthplace: Mansfield, Ohio
• Occupation: Businesswoman
• Invention: Software to secure documents
Janet Emerson Bashen, founder, chief executive officer, and president of human resources company Bashen Corp., in 2006 became the first African American woman in the U.S. to receive a software patent. She and a cousin developed LinkLine, a web-based application that stores and retrieves information pertaining to Equal Employment Opportunity cases.

Jeanne Lee Crews
• Year of birth: 1939
• Birthplace: United States
• Occupation: Inventor/scientist
• Invention: Bumper to shield satellites from space debris
Jeanne Crews joined NASA in 1964 — one of the first women engineers to do so — and began working on the problem of protecting satellites and manned craft from space debris. She developed the “space bumper,” a multi-layered shield that is as light but stronger than aluminum and is still in use on the International Space Station.

Margaret Hamilton
• Year of birth: 1936
• Birthplace: Paoli, Indiana
• Occupation: Computer scientist
• Invention: Software development
Margaret Hamilton led the Software Engineering Division at the MIT Instrumentation Laboratory that developed guidance and navigation software for the Apollo space program. The software was critical to the success of the Apollo missions and was adapted for use in Skylab, the Space Shuttle and the first digital fly-by-wire systems in aircraft. Hamilton coined the very term “software engineering.”

Patricia Billings
• Year of birth: 1926
• Birthplace: Clinton City, Missouri
• Occupation: Sculptor/inventor/businesswoman
• Invention: Geobond-replacement for asbestos
Sculptor Patricia Billings invented Geobond to prevent her works from shattering. She knew that sculptors during the Renaissance used a cement additive to make their plaster more durable and wanted to create a modern version. After years of experimentation, Billings developed Geobond, which creates an indestructible plaster when mixed with gypsum and concrete. What’s more, it is fireproof and non-toxic and thus a practical alternative to asbestos.

Lynn Conway
• Year of birth: 1938
• Birthplace: Mount Vernon, New York
• Occupation: Computer scientist
• Invention: Pioneer of microelectronics chip design
Lynn Conway is more than an inventor — she’s a revolutionary. Along with Carver Mead, Conway is credited with the Mead & Conway revolution, a design process for the integrated circuits that make microchips. She also invented generalized dynamic instruction handling, which is used to improve computer processor performance.

Erna Schneider Hoover
• Year of birth: 1926
• Birthplace: Irvington, New Jersey
• Occupation: Mathematician
• Invention: Invented computerized telephone switching method
While working at Bell Labs in New Jersey, mathematician Erna Hoover invented a way to monitor the frequency of incoming calls and prioritize tasks so as to avoid overloading phone switches. In 1971, she received a patent for a Feedback Control Monitor for Stored Program Data Processing System — one of the first software patents ever issued — and the principles of her invention are still applied in telecommunications equipment today. Hoover also worked on radar control programs for the interception of intercontinental ballistic missile warheads.

Nancy Perkins
• Year of birth: N/A
• Birthplace: N/A
• Occupation: Inventor
• Invention: Invented and improved various household appliances
Nancy Perkins has made a career out of either inventing or improving household appliances. Perkins holds patents for various household items such as a rotary grater for cheese, an upright vacuum cleaner, a buffet server, and a slow cooker, to name just a few.

Edith Marie Flanigen
• Year of birth: 1929
• Birthplace: Buffalo, New York
• Occupation: Chemist
• Invention: Invented or developed over 200 different synthetic substances
Edith Flanigen has been described as one of the most inventive chemists of all time. Over her 42-year career with Union Carbide, she invented more than 200 synthetic substances and was awarded more than 100 patents. Flanigen is known for her work on molecular sieves, which can filter or separate complex substances, and in particular zeolite Y, which is used to refine petroleum. She also co-invented a synthetic emerald that was used in masers, predecessors of lasers, and jewelry.
