Edward Jenner

Edward Jenner

Edward Jenner (17 May 1749 – 26 January 1823) was an English doctor and scientist. He created the world's first vaccine, which protected people from the smallpox disease. The words vaccine and vaccination come from the name he gave to this protection, using cowpox.

In Jenner's time, smallpox was a very serious illness. His discovery helped save many lives. In 1821, he became a doctor for King George IV. He also served as mayor of Berkeley and a justice of the peace. He was a member of the Royal Society.

Jenner is often called "the father of immunology" because his work helped so many people. In 2002, the BBC named him one of the top 100 great people in British history in their list of the 100 Greatest Britons. He also studied animals and made discoveries in zoology, such as how the cuckoo lays its eggs in other birds' nests. This behavior was noted long before by Aristotle in his History of Animals.

Early life

Edward Jenner was born on 17 May 1749 in Berkeley, Gloucestershire, England. He was one of nine children. His father, the Reverend Stephen Jenner, was the vicar of Berkeley, so Jenner had a good basic education.

When Jenner was young, he went to school in Wotton-under-Edge and Cirencester. During this time, Jenner was inoculated for smallpox. At age 13, he began working for seven years with Daniel Ludlow, a surgeon in Chipping Sodbury.

In 1770, Jenner started learning surgery and anatomy with John Hunter at St George's Hospital in London. He returned home in 1773 and became a successful family doctor. In 1792, Jenner earned a degree from the University of St Andrews.

Zoology

Edward Jenner was elected a fellow of the Royal Society in 1788 after studying the life of the nested cuckoo. He showed that baby cuckoos push their host's eggs and chicks out of the nest, not the adult cuckoos. Jenner found that baby cuckoos have a special shape on their backs that helps them do this. His work was published in Philosophical Transactions of the Royal Society.

Jenner's study of animals helped him later when he began his work on vaccines. His knowledge of both human and animal biology was important for his discoveries. Today, many vaccines still use parts from animals like cows, rabbits, and chicken eggs, thanks to the work started by Jenner.

Marriage and human medicine

Edward Jenner married Catherine Kingscote in March 1788. Sadly, she passed away from a sickness in 1815. They had three children together. Jenner finished his medical studies and earned his doctor’s degree in 1792 from the University of St Andrews. He also helped learn more about heart health.

Invention of the vaccine

Inoculation was used in some places, but it could be dangerous. In 1721, Lady Mary Wortley Montagu brought this idea to Britain after seeing it in Constantinople.

Edward Jenner found that if someone had cowpox, a milder illness, they would not get smallpox. On May 14, 1796, Jenner tested this on James Phipps, an eight-year-old boy. He used material from cowpox blisters to keep Phipps safe from smallpox. Later tests proved that Phipps and others were protected from smallpox. Jenner's work created the first vaccine, saving many lives. His discovery was shared and helped protect people all over the world from smallpox.

Later life

Edward Jenner was honored by many important groups for his work. In 1802, he became a member of the American Academy of Arts and Sciences. In 1804, he joined the American Philosophical Society. By 1806, he was also a member of the Royal Swedish Academy of Sciences.

In 1803, Jenner became president of the Jennerian Society in London. This group worked to help stop smallpox by sharing information about vaccination. But the society stopped working together in 1809. Jenner also joined the Medical and Chirurgical Society when it began in 1805, which later became the Royal Society of Medicine. He shared many ideas there.

In 1808, a new group called the National Vaccine Establishment was created with help from the government. Jenner felt he was not treated fairly by the leaders of this group and left his position there.

Later, in 1811, Jenner returned to London and noticed that people who had been vaccinated still got sick with smallpox, but their illness was much less severe. In 1821, he was named a special doctor for King George IV and also became the mayor of Berkeley and a magistrate (a justice of the peace). Jenner kept studying nature throughout his life. In 1823, the year he passed away, he shared his ideas about bird migration with the Royal Society.

Jenner was also a Freemason.

Death

Edward Jenner became ill on 25 January 1823 and passed away the next day at the age of 73. He was buried in the family vault at the Church of St Mary in Berkeley.

Religious views

Edward Jenner was a Christian. He wrote about his faith in his letters. Before he died, he told a friend he wasn't surprised that not everyone thanked him, but he did wonder why people didn't thank God more for the good things he could share with others.

Legacy

In 1980, the World Health Organization said that smallpox was no longer a threat. This was thanks to vaccines and the work of many people. Some old samples of the disease are kept safe in special labs in the Centers for Disease Control and Prevention in Atlanta, United States, and at the State Research Center of Virology and Biotechnology VECTOR in Koltsovo, Novosibirsk Oblast, Russia.

Edward Jenner’s work helped scientists learn how our bodies can fight diseases. In 2002, people in the United Kingdom voted him as one of the 100 Greatest Britons. He has been honored on stamps and has a crater on the moon named after him, called the Jenner crater. In 2025, a play about his life called POX was performed in the garden of his old home.

Monuments and buildings

Edward Jenner’s house in the village of Berkeley, Gloucestershire is now a small museum. It has special items related to his work, including horns from a cow named Blossom. There are statues of Jenner in places like Gloucester Cathedral and Kensington Gardens. Near the village of Uley, a hill is called “Smallpox Hill” because it might have been important for Jenner’s studies.

Many places around the world are named after Jenner, such as villages in Somerset County, Pennsylvania, United States, and a road in Stoke Newington, London. There are also health centers, hospital units, and even a garden named after him. In Tokyo, Japan, a statue was placed in a museum to honor the 100th anniversary of Jenner’s discovery. The minor planet 5168 Jenner is also named in his honor.

Publications

Edward Jenner wrote important books about his work. He published An Inquiry Into the Causes and Effects of the Variolæ Vaccinæ in 1798. In 1799, he wrote Further Observations on the Variolæ Vaccinæ, or Cow-Pox. He shared more in 1800 with A Continuation of Facts and Observations relative to the Variolæ Vaccinæ, and in 1801, he published The Origin of the Vaccine Inoculation. These books helped people learn how to stay safe from a serious disease called smallpox.
