Paul Knight Davis

Paul Knight Davis, 89, passed away on April 30, 2018.

Paul lived a very large life. He spent three years in the Navy where he was awarded the World War II Victory Medal. After the military, he was a passionate and successful inventor, pilot, photographer, engineering consultant, craftsman, father and patriot. 

In 1961, he founded and began operating his company, Pacific Roller Die Company, Inc., where he designed and fabricated large-diameter pipe-manufacturing systems sold globally. He held 11 patents related to his metal-processing equipment, including spiral-corrugated and smooth-wall pipe. 

In 1969, he invented the Davis Pulsating Blood Pump, a piston-and-cylinder artificial heart. He worked with the University of California Medical Center in San Francisco. He and a team of doctors kept a calf alive for five days. This was considered a pioneering effort in the future development of artificial hearts by many in both the medical and engineering fields.

In 1998, he invented and patented a very successful Male Incontinence Clamp (MIC), which restored dignity and freedom of activity for many men here and abroad.

Paul never stopped inventing ways to help better the world. His progressive vision included exploring hydrogen fuel cells, aircraft anti-collision systems and running for public office.

He is survived by his wife of 37 years, JoAnn, and his children: Jim Davis, Kathy Betz, Sally Stevenson, Steve Davis, Jeannette Antognazzi, Dan Davis, Todd Bailey and many grandchildren and great-grandchildren. Paul was predeceased by his parents, John and Helen, and older brother John.

Paul’s life will be celebrated by close family and friends. He is laid to rest at the Newcastle Cemetery in Newcastle, Calif.
