Obit: Robert W. Gore, Inventor of Gore-Tex

Robert W. “Bob” Gore, chairman emeritus of the board of directors of W.L. Gore & Associates, died Sept. 17. He was 83.  

Gore's scientific discoveries spawned Gore-Tex Outerwear and paved the way for advancements in industries as varied as performance fabrics, medical devices, space exploration and filtration. He became chairman emeritus in 2018 after 57 years of service on the Gore board, 30 of those as chairman.

He also was president of Gore from 1976-2000, during which time the company became a billion-dollar enterprise.

In 1996, Gore said: “We plan to leave a legacy to society and to future generations: infants with surgically reconstructed hearts that live because of our medical products; governments of free societies that are better able to protect themselves because of defense products; communities with cleaner and healthier environments because of our filtration and sealant products; And yes, people that just have more fun in the outdoors because of our Gore-Tex Outerwear.”

A Prolific Inventor

Gore's commitment to research and development led to his 1969 discovery of a versatile new polymer form, expanded polytetrafluoroethylene (ePTFE).

The introduction of this groundbreaking new material opened a world of possibilities for products and further innovations. The substance provided myriad new product applications including Gore-Tex Fabrics, the world’s first waterproof breathable outerwear and a product that through the years has become synonymous with the outdoors.

Bob’s ePTFE innovation came about at a period in the late 1960s when the big research challenge for Gore was to develop products for computing, space exploration and defense. Trends in electronics at that time made it clear that miniature integrated circuits were the wave of the future and that less cable would be needed as computers became smaller.

One night in October 1969, Bob was researching a new process for stretching extruded PTFE into pipe-thread tape when he discovered that the polymer could be “expanded.” The discovery followed a series of unsuccessful experiments in which he was attempting to stretch heated rods of PTFE by about 10 percent.

As it turned out, the right conditions for stretching PTFE were counterintuitive. Instead of slowly stretching the heated material, he applied a sudden, accelerating yank that unexpectedly caused it to expand to nearly 1000 percent. This resulted in the transformation of solid PTFE into a microporous structure that was mostly air.

Continued advancement in the technology and application of ePTFE enabled Gore to deliver groundbreaking solutions to a wide array of industries. Today, ePTFE is at the heart of products found everywhere from the depths of space to the inner workings of the human body. Along the way, Bob would be awarded nine patents for his work with fluoropolymers. He was elected to the National Academy of Engineering for his technical achievements and in 2006 was inducted into the National Inventors Hall of Fame.

Early Life

Born on April 15, 1937, in Salt Lake City, Utah, Gore was the oldest of five children of Wilbert L. (Bill) and Genevieve W. (Vieve) Gore, founders of W. L. Gore & Associates (Gore).

Gore joined the DuPont workforce after World War II and ultimately was transferred to DuPont’s Experimental Station in Delaware. In 1976, Bob succeeded his father as president and CEO of Gore. 

He is survived by his wife Jane and a large family of children, grandchildren and great-grandchildren, as well as four siblings (Susan Gore, Ginger Giovale, David Gore, Betty Snyder) and extended family.

Memorial plans are yet to be announced.
