The Women Behind Our Best Tech

March 13, 2024

As we celebrate Women's History Month, we'd like to shine a spotlight on the remarkable contributions of women everywhere, especially in the world of STEM. Women have spearheaded a wealth of groundbreaking innovations that have impacted the course of history and technology today. From pioneering new tech to improving everyday conveniences, this special edition blog will delve into a few of the ingenious inventions of women that have left an indelible mark on society. 

Wi-Fi Technology 

Hedy Lamarr, an Austrian-American actress and inventor, co-patented a frequency-hopping spread spectrum communication system in 1942. This system, designed to prevent the jamming of torpedo guidance signals during World War II, laid the groundwork for modern Wi-Fi technology by enabling efficient wireless communication through dynamic frequency switching. 

Computer Algorithm for DNA Analysis 

British biophysicist Rosalind Franklin contributed significantly to the modern understanding of molecular structures, including DNA and RNA. Her research laid the foundation for computer algorithms applied in DNA analysis, aiding in gene sequencing, genetic engineering, medical diagnostics, and forensic criminology, revolutionizing the study of genetics and molecular biology across many sciences. 

Centralized Heating System 

African-American inventor Alice Parker patented a revolutionary centralized heating system fueled by natural gas or oil in 1919. Her innovation transformed home comfort by providing efficient, accessible, and convenient heating. Parker's design laid the groundwork for modern heating systems, enhancing residential and commercial comfort while reducing energy consumption and improving indoor air quality. 


Stephanie Kwolek, an American chemist working for DuPont, invented Kevlar in 1965. This high-strength synthetic fiber, with its remarkable tensile strength and heat resistance, found applications in bullet-resistant vests, aerospace components, tires, and even sports equipment. Kwolek's discovery revolutionized industries requiring lightweight yet durable materials for safety and performance. 

Square-bottomed Paper Bag 

We’ve all used a brown paper bag in our lives, and they are usually seen at groceries stores or school lunch tables across America. Interestingly, American inventor Margaret Knight is to credit for the development of a machine in the 19th century capable of mass-producing the square-bottomed paper bag of an improved design. This innovation revolutionized packaging, providing a sturdy and convenient alternative to traditional bags, and became an enduring staple in the industry.
