James Robert Cade (September 26, 1927 – November 27, 2007) was an American physician, university professor, research scientist and inventor. Cade, a native of Texas, earned his bachelor and medical degrees at the University of Texas, and became a professor of medicine and nephrology at the University of Florida. Although Cade engaged in many areas of medical research, he is most widely remembered as the leader of the research team that created the sports drink Gatorade.Arline Phillips-Han, "Dr. Robert Cade . . . saga of the world's best-selling sports drink and the creative physician scientist behind it," Health Science Center News, University of Florida (February 24, 2003). Retrieved December 10, 2014. Gatorade went on to have significant medical applications for treating dehydration in patients, and has generated over $500 million in royalties for the university.

In his later years, Cade became a prominent philanthropist, donating significant sums to charities affiliated with the Lutheran Church, creating scholarships and donating freely to the University of Florida and other colleges and universities, and endowing his own charitable foundations. He established the Cade Museum for Creativity and Invention in Gainesville, Florida.

Early life and education

Robert Cade was born in San Antonio, Texas, on September 26, 1927.Douglas Martin, "J. Robert Cade, the Inventor of Gatorade, Dies at 80," The New York Times (November 28, 2007). Retrieved December 10, 2014. He was a fourth-generation Texan.Samuel Proctor, Dr. James Robert Cade Interview, Samuel Proctor Oral History Project, George A. Smathers Libraries, University of Florida, Gainesville, Florida, page 4 (1996). Retrieved December 10, 2014. Cade took an early interest in athletics and ran the mile in four minutes, twenty seconds at Brackenridge High School, a very respectable time for a high school athlete in the early 1940s.By way of comparison, Roger Bannister, a British track and field athlete who was the world record-holder in the mile run in the early 1950s and the first to run the mile in less than four minutes, did not do so until 1954. He graduated from Brackenridge High School in May 1945 and joined the U.S. Navy. He served for three years and was stationed at Naval Medical Research Unit Four in Dublin, Georgia (1 year), the destroyer USS Gherardi ( years) and the cruiser USS Rochester. He completed his service in September 1948 with the rank of pharmacist's mate third class.Proctor, Cade Interview, pp. 4–9.

After being discharged from the navy, he enrolled in the University of Texas.Associated Press, "Inventor of Gatorade dies at 80," USA Today (November 27, 2007). Retrieved December 10, 2014.

He also served fellowships at his alma mater, Southwestern Medical School, and Cornell University Medical College in New York City. In 1961, Cade joined the faculty of the University of Florida College of Medicine in Gainesville, Florida, as an assistant professor of internal medicine in its renal division.Proctor, Cade Interview, pp. 39–43.

Invention of Gatorade

In 1965, Cade was approached by Dewayne Douglas, an assistant coach for the Florida Gators football team, about the extreme dehydration faced by Gator football players practicing in the high temperatures and humidity of the Deep South in late summer and early fall.Michael McLeod, "Gator-made," Orlando Sentinel (August 14, 2005). Retrieved February 17, 2010. Douglas questioned Cade why his football players did not urinate during practice and games. Cade learned from anecdotal evidence that football players were losing water through perspiration and failing to replace fluid during practice and games. Cade's research team discovered that football players were losing up to 18 pounds (8.2 kilograms) during the three hours of a college football game, and that ninety to ninety-five percent of that loss was water. A player's plasma volume could decrease as much as seven percent and blood volume by five percent, and sodium and chloride were excreted in the sweat.

During 1965 and 1966, Cade, together with his team of research doctors Dana Shires, James Free, and Alejandro M. de Quesada, conducted a series of trial-and-error experiments with his glucose-and-electrolytes rehydration drink on members of the Gators football team of coach Ray Graves, first with members of the freshman squad, and after initially promising results, with starting members of the varsity team. "It didn't taste like Gatorade," Cade said in a 1988 interview with Florida Trend magazine. In fact, according to Cade, when Gators lineman Larry Gagner first tried it, he spat it out and strongly suggested that the original experimental formula tasted more like bodily waste.Proctor, Cade Interview, pp. 68–69. Dana Shires remembered that "it sort of tasted like toilet bowl cleaner.""Robert Cade: Scientist who invented Gatorade, the world's first and biggest-selling sports drink," The Times (November 29, 2007). Retrieved December 14, 2014. To make it more palatable, at the suggestion of Cade's wife, the researchers added lemon juice and cyclamateRichard Burnett, "Gatorade Inventor: My Success Based On Sweat And Luck," Orlando Sentinel (April 16, 1994). Retrieved February 16, 2010. Other sweeteners were substituted in 1970, when the federal Food and Drug Administration (FDA) banned cyclamate as a potential carcinogen. to the original formula of water, salt, sodium citrate, fructose and monopotassium phosphate.

However, the rehydration drink was first known as "Cade's Ade"Samuel Proctor & Wright Langley, Gator History: A Pictorial History of the University of Florida, South Star Publishing Company, Gainesville, Florida, p. 150 (1986). and "Cade's Cola" to the Florida Gators football team, and only later became known as "Gatorade." The drink received its first real test in the Gators' 1965 game against the LSU Tigers football team; the Tigers faded in the heat of the second half and the Gators did not. Coach Graves was convinced, and asked Cade to produce enough of his potion for all Gator games. Gatorade achieved national prominence as a result of the Gators' first Orange Bowl title over the Georgia Tech Yellow Jackets in January 1967. The Gators reinforced their reputation as a "second-half team" and came from behind to defeat the Yellow Jackets 27–10.College Football Data Warehouse, All-Time Coaching Records, Ray Graves 1966 . Retrieved February 19, 2010. Afterward, Georgia Tech head coach Bobby Dodd told reporters: "We didn't have Gatorade; that made the difference."

Cade patented the formula and offered all the rights to the drink to the University of Florida in exchange for the university's backing of the production and marketing of the drink, but the university turned down his proposal.Massachusetts Institute of Technology, Inventor of the Week Archive, Inventor of the Week: Robert Cade. Retrieved December 10, 2014. He initially obtained bank financing and began to produce "Gatorade" through his own business, but later entered into a contract with Stokely-Van Camp, Inc. to produce and sell the drink. When sales royalties reached $200,000, the university took notice.Dave Curtis, "," Orlando Sentinel (April 14, 2007). Retrieved July 12, 2022. The Florida Board of Regents, prompted by the U.S. Department of Health, Education and Welfare, which had provided Cade with a small grant for his research, asked for the patent rights.Julian M. Pleasants, Gator Tales: An Oral History of the University of Florida, University of Florida, Gainesville, Florida, pp. 129–130 (2006). Cade refused. The Board of Regents, acting on behalf of the university, then brought suit against Cade for a share of the profits, arguing that the university's facilities, employees and students were instrumental in the development of the product.Proctor & Langley, Gator History, p. 55. After thirty-one months of legal wrangling, Cade and the university negotiated a settlement of their dispute in 1972, and the Board of Regents and the university settled for a twenty percent share of the royalties. Cade, and his investors in the Gatorade Trust, retained eighty percent. In the aftermath of the settlement, Cade and the university resolved their differences amicably, and expanded their professional relationships—of the first $70,500 in Gatorade royalties received by the university, the university reinvested $30,000 in kidney research by Cade's renal department and another $12,000 in Cade's other research projects."Gatorade To Aid UF Research," St. Petersburg Times, p. 12B (February 8, 1973). Retrieved March 22, 2010. Cade, for his part, created multiple scholarships and contributed generously to the university from his own royalties over the following years.

Legacy Up to 2007, the University of Florida has received over $150 million from its share of the Gatorade royalties.Jack Stripling, "Dr. Robert Cade, Gatorade inventor, dies at 80," The Gainesville Sun (November 27, 2007). Retrieved December 10, 2014.The University of Florida has since become one of the largest public research universities in the United States, and derives significant annual income from the patent royalties generated by the inventions of its professors and other research staff. See, e.g., Mike Thomas, "Gator Aid: What UF Is Thirsty For," Orlando Sentinel (May 7, 1989). Retrieved December 10, 2014. As of 2015, this total has increased to $281 million. Cade and his associates' share of the royalties is undisclosed, the majority of their rights having been sold to Stokely-Van Camp. After the settlement, Cade continued to work for the university, and the college of medicine named him professor emeritus of nephrology upon his retirement in 2004.
