Фредерик Бэнтинг: Инсулиннің ашқан және Нобель сыйлығының иегері

Canadian medical scientist and doctor

Sir Frederick Grant Banting (November 14, 1891 – February 21, 1941) was a Canadian pharmacologist, orthopedist, and field surgeon. For his co discovery of insulin and its therapeutic potential, Banting was awarded the Nobel Prize in Physiology or Medicine with John Macleod. Banting and his student, Charles Best, isolated insulin at the University of Toronto in the lab of Scottish physiologist John Macleod. When he and Macleod received the 1923 Nobel Prize in Physiology or Medicine, Banting shared the honours and award money with Best. That same year, the government of Canada granted Banting a lifetime annuity to continue his work. To this day, Frederick Banting, who received the Nobel Prize at age 32, remains the youngest Nobel laureate for Physiology/Medicine.

Banting was born on November 14, 1891, in his family's farmhouse in Essa, Ontario, two miles from nearby Alliston. He was the youngest of five children of William Thompson Banting, a farmer in Tecumseh, and Margaret Grant, the daughter of a mill manager. The Bantings were a financially stable family of British and Northern Irish origin. Banting's distant relative, the London based undertaker William Banting, popularised a weight loss diet in 1864, and the word "Banting" entered the Oxford English Dictionary as its description. His mother's relatives, the Grants, were of Scottish descent. With his family being located within a secure rural community, Banting was raised in prosperous circumstances. He was often called "Fred" or "Freddie." Farm life largely defined most of his boyhood. He felt excluded from his siblings, all multiple years his senior, and recalled that "my older brothers could not be bothered with me for the most part." When he began schooling at the age of seven in Alliston, Banting was a shy, asocial boy who tired of the attendance and was bullied frequently. Early difficulties with spelling ensured poor marks in exams: "I simply could not spell. Every word seemed to have about three ways of spelling. It was a guess and I invariably guessed wrong." He later attributed these experiences as being the product of an inferiority complex. During his childhood, Banting devoted himself to farmwork, grew close with his mother, and sympathised with animals in the absence of other company. Marion Walwyn, a cousin who first met Banting in 1901, recalled that "we sat together in the swing in our yard. In an hour he didn’t say one word." He continued to struggle in school and stubbornly resisted being disciplined there. After one incident, he resolved never to continue his education but was convinced otherwise by his father. Banting's grandfather, John Banting, had urged his own children to be educated; the philosophy had influenced William, who offered to provide a fund to his sons when they turned twenty one. In contrast to his brothers, who spent the inheritance towards their own farms, Frederick would use it towards matriculation. In his late teenage years, Banting grew into a tall man with engagements in school football and baseball teams. Both his mother and father hoped that he would find a vocation in the Methodist ministry. He passed physics and chemistry during junior matriculation examinations in 1909, but repeated English and was required to undertake French and Latin. The next year, he narrowly passed Latin but failed French and, for a second time, English composition. The principal later remembered his repeated efforts: "We would not have picked him for one on whom fame should settle. He was a white boy, a right boy."

Banting finally passed examinations in July of 1910. He stated on his application to university that he wished to be a teacher, although he also harbored aspirations of becoming a doctor. He toured the Canadian West for the summer, traveling to Winnipeg and Calgary, before enrolling at the University of Toronto, where he entered the General Arts course at Victoria College. Despite hard work, Banting failed his first year, but decided to become a doctor and returned to repeat the year. He petitioned to join the medical program in February 1912 and was accepted. In September, he dropped out of Victoria College to begin medical school at the University of Toronto. Banting established himself in medical school by working diligently. His roommate, Sam Graham, remembered him for studying late into the night. Besides being a successful rugby player, however, he was otherwise undistinguished. His grades—now without the burden of language courses—saw a marked improvement, averaging approximately a B, an above average score. Summers were spent returning to work at the farm. At Toronto's Faculty of Medicine, Banting specialised in surgery. At the onset of World War I, Banting, along with most Canadian men, sought to enlist in the army. He attempted to enter the Canadian Expeditionary Force on August 16, 1914, the day after Canada's declaration of war, and then again in October, but was refused twice due to poor vision. In his third year of medical school Banting successfully joined the Royal Canadian Army Medical Corps in 1915 and was commissioned a private, then promoted to sergeant. He trained at a camp at Niagara Falls for the summer before his fourth year of school. The university accelerated the class by condensing the fifth year of medical school during the summer of 1916. The curriculum placed more emphasis on surgical procedure and trauma; a lecture dedicated to the treatment of diabetes derived itself from Frederick Madison Allen of the Rockefeller Institute, who recommended that diabetics be placed on a starvation diet for minimum metabolization. Banting's fourth year was committed to clinical work at Toronto General Hospital. Under the guidance of Clarence L. Starr, the chief surgeon at the Hospital for Sick Children, Banting gained training as an undergraduate house surgeon. By 1915, he had definitively resolved to practice surgery, performing his first operation—the drainage of a soldier's abscess—next winter. On December 9, 1916, Banting graduated with his Bachelor of Medicine (M. B.) and reported for military duty the next day. He studied orthopedic medicine and, in 1919–1920, was Resident Surgeon at The Hospital for Sick Children. Banting was unable to gain a place on the hospital staff and so he decided to move to London, Ontario, to set up a medical practice. From July 1920 to May 1921, he continued his general practice, while teaching orthopedics and anthropology part time at the University of Western Ontario in London because his medical practice had not been particularly successful. From 1921 to 1922 he lectured in pharmacology at the University of Toronto. He received his M. D. degree in 1922, and was also awarded a gold medal.

An article he read about the pancreas piqued Banting's interest in diabetes. Banting had to give a talk on the pancreas to one of his classes at the University of Western Ontario on November 1, 1920, and he was therefore reading reports that other scientists had written. Research by Naunyn, Minkowski, Opie, Sharpey Schafer, and others suggested that diabetes resulted from a lack of a protein hormone secreted by the islets of Langerhans in the pancreas. Schafer had named this putative hormone "insulin". The hormone was thought to control the metabolism of sugar; its lack led to an increase of sugar in the blood which was then excreted in urine. Attempts to extract insulin from ground up pancreas cells were unsuccessful, likely because of the destruction of the insulin by the proteolysis enzyme of the pancreas. The challenge was to find a way to extract insulin from the pancreas prior to its destruction. Pork and beef would remain the primary commercial sources of insulin until they were replaced by genetically engineered bacteria in the late 20th century. On January 11, 1922, the first ever injection of insulin was given to 14 year old Canadian Leonard Thompson at Toronto General Hospital. In spring of 1922, Banting established a private practice in Toronto and began to treat diabetic patients. His first American patient was Elizabeth Hughes Gossett, daughter of U. S. Secretary of State Charles Evans Hughes. Banting and Macleod were jointly awarded the 1923 Nobel Prize in Physiology or Medicine. Banting split his half of the Prize money with Best, and Macleod split the other half of the Prize money with James Collip.

Banting was appointed Senior Demonstrator in Medicine at the University of Toronto in 1922. Next year he was elected to the new Banting and Best Chair of Medical Research, endowed by the Legislature of the Province of Ontario. He also served as Honorary Consulting Physician to the Toronto General, the Hospital for Sick Children, and the Toronto Western Hospital. At the Banting and Best Institute, he focused his research on silicosis, cancer, and the mechanisms of drowning. In 1938, Banting's interest in aviation medicine resulted in his participation with the Royal Canadian Air Force (RCAF) in research concerning the physiological problems encountered by pilots operating high altitude combat aircraft. Banting headed the RCAF's Number 1 Clinical Investigation Unit (CIU), which was housed in a secret facility on the grounds of the former Eglinton Hunt Club in Toronto. During the Second World War he investigated the problems of aviators, such as "blackout" (syncope). Returning from the trip, Banting gave an interview in Montreal with a Toronto Star reporter under the agreement that his statements on HBC would remain off the record. The conversation was nonetheless published in the Toronto Star and rapidly reached a wide audience across Europe and Australia. Banting was angry at the leak, having promised the Department of the Interior not to make any statements to the press prior to clearing them. The navigator and co pilot died instantly, but Banting and the pilot, Captain Joseph Mackey, survived the initial impact. According to Mackey, the sole survivor, Banting died from his injuries the next day. Banting was en route to England to conduct operational tests on the Franks flying suit developed by his colleague Wilbur Franks. Banting and his wife are buried at Mount Pleasant Cemetery in Toronto.

Banting developed an interest in painting beginning around 1921 while he was in London, Ontario. Some of his first pieces were done on the back of the cardboard in which his shirts were packed by the dry cleaners. He became friends with the Group of Seven artists A. Y. Jackson and Lawren Harris, fellow members of the Arts and Letters Club of Toronto, sharing their love of the rugged Canadian landscape. Writing on Banting, Jackson recalls that "He did not want to make a business of art and would tell [would be purchasers] to go buy a Lismer or something else and then he would exchange it for one of his." At the time of his death in 1941, Banting was one of Canada's best known amateur painters.

In 1994, Banting was inducted into the Canadian Medical Hall of Fame. In 2004, he was nominated as one of the top 10 "Greatest Canadians" by viewers of the Canadian Broadcasting Corporation. When the final votes were counted, Banting finished fourth behind Tommy Douglas, Terry Fox and Pierre Trudeau.

Banting's namesake, the Banting Research Foundation, was created in 1925 and provides funding to support health and biomedical research in Canada. Banting's name is immortalized in the yearly Banting Lectures, given by an expert in diabetes, and by the creation of the Banting and Best Department of Medical Research of the University of Toronto; Sir Frederick G Banting Research Centre located on Sir Frederick Banting Driveway in the Tunney's Pasture complex, Ottawa, ON; Banting Memorial High School in Alliston, ON; Sir Frederick Banting Secondary School in London, ON; Sir Frederick Banting Alternative Program Site in Ottawa, ON; Frederick Banting Elementary School in Montréal Nord QC and École Banting Middle School in Coquitlam, BC. The "Major Sir Frederick Banting, MC, RCAMC Award for Military Health Research", sponsored by the True Patriot Love Foundation, is awarded annually by the Surgeon General to the researcher whose work presented at the annual Military and Veterans Health Research Forum is deemed to contribute most to military health. It was first awarded in 2011 in the presence of several Banting descendants. The "Canadian Forces Major Sir Frederick Banting Term Chair in Military Trauma Research" at Sunnybrook Health Sciences Centre was established in 2012. The first Chair holder is Colonel Homer Tien, medical director of Sunnybrook's Tory Regional Trauma Centre and Senior Specialist and Trauma Adviser to the Surgeon General. The Banting Postdoctoral Fellowship Program is administered by the Canadian Institutes of Health Research, the Natural Sciences and Engineering Research Council of Canada, and the Social Sciences and Humanities Research Council of Canada. The fellowship provided up to two years of funding at $70,000 per year to researchers in health, natural sciences, engineering, social sciences and humanities.

Banting House, his former home located in London, Ontario, was declared a National Historic Site of Canada in 1997. The house contains a museum of the history of insulin, as well has Banting's artwork. The Banting Interpretation Centre in Musgrave Harbour, Newfoundland and Labrador is a museum named after him which focuses on the circumstances surrounding the 1941 plane crash which claimed his life. The crater Banting on the Moon is also named after him for his contributions to medicine. During the voting for "Greatest Canadians" in late 2003, controversy rose over the future use of the Banting family farm in New Tecumseth which had been left to the Ontario Historical Society by Banting's late nephew, Edward, in 1998. The dispute centred on the future use of the property and its buildings. In a year long negotiation, assisted by a provincially appointed facilitator, the Town of New Tecumseth offered $1 million to the Ontario Historical Society (OHS). The town intended to turn the property over to the Sir Frederick Banting Legacy Foundation for preservation of the property and buildings, and the Legacy Foundation planned to erect a Camp for Diabetic Youths. The day after the November 22, 2006, deadline for the OHS to sign the agreement, the OHS announced that it had sold the property for housing development to Solmar Development for more than $2 million. The Town of New Tecumseth announced it would designate the property under the Ontario Heritage Act. This would prevent its commercial development and obligate the owner to maintain it properly. OHS objected. The Ontario Conservation Review Board heard arguments for and against designation in September 2007 and recommended designation of the entire property in October. The Town officially passed the designation by law on November 12, 2007. Banting's artwork has gained attention in the art community; A painting of his called "St. Tîte des Cap" sold for Can$30,000 including buyer's premium at a Canadian art auction in Toronto.

He and his insulin discovery have also been depicted in various media formats, including comic books, the biography by Michael Bliss, and on television. The National Film Board of Canada produced a short film in 1958, The Quest. The 1988 television movie Glory Enough for All depicted the search for insulin by Banting and Best, with R. H. Thomson starring as Banting. Banting is also portrayed by Jason Priestley boarding his fatal flight in the 2006 historical drama Above and Beyond.

Prior to the award of the Nobel Prize in Physiology or Medicine for 1923—which he shared with Macleod—he received the Reeve Prize of the University of Toronto (1922). In 1923, the Canadian Parliament granted him a Life Annuity of $7,500. King George V In 2004, Banting was inducted into the National Inventors Hall of Fame.

A "Flame of Hope" was lit by Her Majesty Queen Elizabeth the Queen Mother in 1989 as a tribute to Dr. Frederick Grant Banting and all the people that have lost their lives to diabetes. The flame will remain lit until there is a cure for diabetes. When a cure is found, the flame will be extinguished by the researchers who discover the cure. The flame is located at Sir Frederick Banting Square in London, Ontario, Canada beside the Banting House National Historic Site of Canada.

A time capsule was buried in the Sir Frederick Banting Square in 1991 to honour the 100th anniversary of Sir Frederick Banting's birth. It was buried by the International Diabetes Federation youth representatives and Governor General of Canada Ray Hnatyshyn. It will be exhumed if a cure for diabetes is found.

Since 1941, the American Diabetes Association confers Banting Medals for those with long term contribution to diabetes research and treatment. In 1991, International Diabetes Federation and World Health Organization (WHO) made his birthday the World Diabetes Day. On November 14, 2016, Google celebrated his 125th birthday with a Google Doodle. 2021 marks the centenary of Dr. Banting's co discovery of insulin at the University of Toronto. Canada Post issued a commemorative stamp.
