Sixteen innovation pioneers whose inventions range from wheelchair technology to aromatase inhibitors will be honored as part of the 50th class of National Inventors Hall of Fame (NIHF) Inductees.
In partnership with the United States Patent and Trademark Office (USPTO), NIHF will honor these Inductees on Oct. 26, 2023, at one of the innovation industry’s most highly anticipated events — “The Greatest Celebration of American Innovation.” The event also will celebrate the 50th anniversary of NIHF’s founding in 1973, when Thomas Edison was the sole Inductee.
“It is an honor for the USPTO to recognize the 2023 class of the National Inventors Hall of Fame. We are proud to be a 50-year partner with NIHF, and we look forward to working together to support and recognize our world-changing innovators and entrepreneurs.”
— Kathi Vidal, Under Secretary of Commerce for Intellectual Property and Director of the USPTO
The Class of 2023
Marjorie Stewart Joyner: Permanent Wave Machine (Posthumous). Marjorie Stewart Joyner invented a permanent wave machine in the 1920s. A beautician, salon owner, instructor, and executive for the Madam C. J. Walker Co., she established beauty industry standards and powerfully advocated for civil rights.
Rodolphe Barrangou and Philippe Horvath: CRISPR-enhanced Food Products. Molecular biologists Rodolphe Barrangou and Philippe Horvath discovered that CRISPR sequences and associated proteins comprise an acquired immune system in bacteria. Applying their research to enhance starter cultures in the dairy industry, they improved the world’s food supply and laid the foundation for the field of gene editing.
Robert G. Bryant: LaRC-SI (Langley Research Center-Soluble Imide). A NASA chemist, Robert Bryant developed LaRC-SI (Langley Research Center-Soluble Imide), a polymer used as an insulation material for leads in implantable cardiac resynchronization therapy devices. LaRC-SI enables small, flexible, reliable leads that are easier to implant, benefiting patient outcomes.
Emmanuelle Charpentier and Jennifer Doudna: CRISPR-Cas9 Gene Editing. Microbiologist Emmanuelle Charpentier and biochemist Jennifer Doudna co-invented the gene-editing system CRISPR-Cas9, creating a versatile technology that provided the means to edit genes on an unprecedented scale with extremely high precision. For this work, they won the Nobel Prize in Chemistry in 2020.
Lynn Conway: Very Large-Scale Integration (VLSI). Lynn Conway and NIHF Inductee Carver Mead transformed the global microelectronics industry with their invention of VLSI, or Very Large-Scale Integration. This revolutionary technology, detailed in their groundbreaking textbook “Introduction to VLSI Systems,” allowed small teams of individuals to design powerful chips.
Rory Cooper: Wheelchair Technology. Biomedical engineer Rory Cooper’s innovations have improved manual and electric wheelchairs, and advanced the health, mobility and social inclusion of people with disabilities and older adults. His research has been informed by his own experience as a disabled U.S. Army veteran.
Katalin Karikó and Drew Weissman: Modified mRNA Technology Used in COVID-19 Vaccines. Fundamental research by biochemist Katalin Karikó and immunologist Drew Weissman laid a critical piece of the foundation for the mRNA COVID-19 vaccines developed by Pfizer-BioNTech and Moderna. Crucial in the fight against the coronavirus pandemic, several billion mRNA vaccine doses have been administered worldwide since December 2020.
Luis von Ahn: reCAPTCHA. Computer scientist Luis von Ahn co-invented the website security program CAPTCHA, or Completely Automated Public Turing test for telling Computers and Humans Apart. He then created reCAPTCHA, furthering this work while assisting in digitizing books and other archives. He also co-founded Duolingo, whose online platform is the world’s most popular way to learn languages.
Angela Hartley Brodie: Aromatase Inhibitors (Posthumous). Angela Hartley Brodie discovered and developed a class of drugs called aromatase inhibitors, which can stop the production of hormones that fuel the growth of cancer cells. Aromatase inhibitors are among the leading therapies against breast cancer.
Cyril Keller and Louis Keller: Bobcat Skid-Steer Loader (Posthumous). Brothers Cyril and Louis Keller played a key role in launching the compact equipment industry in the late 1950s and early 1960s with their invention of the world’s first compact loader, which became the Bobcat skid-steer loader.
James A. Parsons Jr.: Durimet 20 Stainless Steel Alloy (Posthumous). Metallurgist James A. Parsons Jr. created corrosion-resistant, stainless steel alloy Durimet 20. Invented in the 1930s, the alloy is still widely used today in industrial processes that involve corrosive chemicals.
Roger Tsien: Green Fluorescent Protein (GFP) Variants (Posthumous). Biochemist Roger Tsien invented green fluorescent protein (GFP) variants. For his contributions to creating a full palette of fluorescent proteins that enable scientists to track multiple cellular processes simultaneously, he shared the 2008 Nobel Prize in Chemistry.
