This Weekend in History on January 10 and 11: First Successful Insulin Treatment of Diabetes

On January 10, 1920, the Treaty of Versailles officially took effect, bringing World War I’s peace settlement into force and setting new rules for how Europe would be organized after the war. At the time, it mattered because it confirmed Germany’s defeat, reshaped borders, created new states, and established the League of Nations in the hope that future wars could be prevented through diplomacy. It still matters today because many of the treaty’s choices—about territory, security, reparations, and international cooperation—helped shape the unstable politics of the interwar years. The treaty’s legacy is often discussed not as a single “cause” of later conflict, but as one major piece of a complicated postwar landscape that influenced how countries and people understood justice, responsibility, and peace.

In the years leading up to 1920, Europe had been exhausted by four years of industrial-scale war. Millions had died, economies were strained, and old empires were collapsing. When the treaty took effect on this date, it made the postwar order more than a set of promises on paper. Germany faced limits on its military and accepted responsibility clauses that were politically explosive at home. New borders affected communities that suddenly found themselves in different countries than before, often without moving at all. The League of Nations, also activated through the treaty framework, represented an early attempt at a permanent international forum for resolving disputes, even though the League’s power and membership limits would later become clear.

The same date has also marked turning points in politics far from Europe. On January 10, 1946, the first meeting of the United Nations General Assembly opened in London. The UN was created after World War II with the aim of reducing the risk of another global conflict, encouraging cooperation, and addressing humanitarian needs. This first session mattered because it signaled that many countries wanted a standing place to debate problems openly rather than rely only on wartime alliances or ad hoc negotiations. Over time, the UN has become a central venue for international discussion—sometimes effective, sometimes constrained by competing interests—but consistently important as a shared diplomatic framework.

A different kind of political shift unfolded on January 10, 1957, when Harold Macmillan became prime minister of the United Kingdom after Anthony Eden resigned in the wake of the Suez Crisis. The change in leadership came at a moment when Britain was reassessing its role in a world where former colonies were gaining independence and Cold War pressures were rising. Macmillan’s term would be shaped by decolonization, economic policy debates, and efforts to navigate alliances, reflecting how mid-20th-century power relationships were being renegotiated.

Culture and media history also finds a foothold on this date. On January 10, 1927, the silent film era reached a major peak with the premiere of Metropolis in Germany. Directed by Fritz Lang, it presented a striking vision of a futuristic city shaped by technology, class divisions, and industrial power. At the time, it stood out for its ambitious sets and special effects, and it pushed the boundaries of what film could look like and what it could discuss. Its long-term impact is visible in later science fiction movies, architecture-inspired design, and the way visual storytelling can explore social questions without relying on dialogue.

Sports history adds another thread. On January 10, 1962, the first official match of the American Football League (AFL) All-Star Game was played (with earlier AFL seasons having begun in 1960). While the AFL itself was short-lived as a separate league, it played a major role in reshaping professional American football through competition, new markets, and eventual merger with the NFL. That merger helped create the modern structure of the sport in the United States, including the Super Bowl era that followed. Even for readers who do not follow American football, the AFL story illustrates how rival organizations can drive change through innovation and competition.

January 10 has also been tied to moments of social change and public attention. In 1984, the United States and the Vatican established full diplomatic relations. For decades, formal ties had been limited, shaped by domestic political debates and international concerns. The 1984 decision reflected a broader pattern of states reassessing how to engage with influential non-state actors and religious institutions in global affairs. The long-term significance is less about a single policy shift and more about how diplomacy adapts to the realities of influence, soft power, and international networks.

Not every important event on this date is centered on governments or institutions. Disasters and accidents, while painful, often lead to lasting changes in safety and policy. On January 10, 1920, a streetcar accident in Brooklyn, New York, killed multiple people when a train derailed and plunged into a cut—an example of the risks that came with rapidly growing urban transit systems in the early 20th century. Tragedies like this helped push public pressure for improved infrastructure, better oversight, and stronger engineering standards, changes that would gradually make mass transit safer in many cities.

Notable births on January 10 span politics, arts, and sport, showing how one date can connect very different lives.

George Foreman, born January 10, 1949, became one of boxing’s defining heavyweight champions. He is remembered not only for his power in the ring, but also for an unusual career arc: after stepping away, he returned years later and regained a world title at an age when most fighters are long retired. His story is often cited in sports history as a rare example of longevity and reinvention at the highest level.

Rod Stewart, born January 10, 1945, became a major figure in popular music, known for a distinctive voice and a career that crossed rock, pop, and soul influences. His long run of hits and sustained touring career reflect the postwar expansion of mass media and recorded music, as radio, television, and global distribution turned singers into international cultural figures.

Sal Mineo, born January 10, 1939, was an American actor who gained wide attention in the 1950s and 1960s. He is remembered for performances that captured youth culture and social tensions of the era, particularly in films that explored generational conflict and identity. His career points to how Hollywood both shaped and responded to changing attitudes in mid-century society.

Notable deaths on January 10 include figures whose work left durable marks on literature, diplomacy, and public life.

Gabriela Mistral, who died on January 10, 1957, was a Chilean poet, educator, and diplomat, and the first Latin American writer to receive the Nobel Prize in Literature. Her writing often addressed love, loss, childhood, and social responsibility in language that could be both simple and profound. Beyond literature, her role in education and public service made her a symbol of cultural and civic contribution in Latin America and beyond.

Coco Chanel, who died on January 10, 1971, was a French fashion designer whose ideas helped reshape women’s clothing in the 20th century. She is remembered for designs that emphasized practicality and modern lines, and for building a fashion house that became globally influential. Her legacy is tied to how clothing, industry, and cultural taste can change together, reflecting shifting lifestyles and expectations.

January 10, taken as a whole, shows how history is built from many kinds of turning points.

On January 11, 1922, doctors in Toronto gave 14-year-old Leonard Thompson the first successful treatment with insulin, turning a fast-moving, often fatal disease into something medicine could manage. Thompson had type 1 diabetes, and at the time there was little doctors could do beyond strict diets that only slowed decline. The early insulin extract did not work perfectly at first, but it proved the idea—and within days a purer dose helped him improve. This moment mattered immediately because it offered real hope to patients and families who had been watching diabetes take lives in months. It still matters today because insulin therapy became a foundation of modern endocrinology and a model for how laboratory discoveries can rapidly change everyday health care worldwide.

The path to that breakthrough had been building for decades. In the late 1800s and early 1900s, researchers linked the pancreas to blood sugar control, but isolating the right substance was difficult. In 1921, Frederick Banting and Charles Best, working in John Macleod’s lab at the University of Toronto, extracted a hormone from pancreatic tissue. Biochemist James Collip then helped refine it into a safer, more effective form. On this date in 1922, the science moved from the lab to the bedside, and the results were strong enough to launch wider production. Over time, insulin was standardized, mass-produced, and improved—first from animal sources and later through recombinant DNA technology—saving millions of lives and reshaping how chronic illness is treated.

Long before insulin changed medicine, January 11 had already seen turning points in politics and war. In 1569, the first recorded lottery in England was drawn in London. It was meant to raise funds for public works and other needs, reflecting a growing idea in early modern Europe: governments and cities needed new ways to finance infrastructure and social obligations. Lotteries would later spread widely, sometimes supporting civic projects and sometimes fueling controversy, but they became a lasting tool for public fundraising.

In 1693, a powerful natural disaster struck in southern Italy and Sicily when a major earthquake hit the region. The quake and resulting damage devastated towns and caused enormous loss of life. Beyond the immediate tragedy, the rebuilding influenced architecture and urban planning, including the spread of Baroque styles in parts of Sicily. Events like this also shaped early efforts to document earthquakes systematically, laying groundwork for later seismology and building standards in quake-prone areas.

The 20th century brought January 11 into the story of global conflict. In 1942, during World War II, Japan invaded the Dutch East Indies (now Indonesia), targeting oil and other resources critical to sustaining its war effort. The campaign quickly changed the balance of power in Southeast Asia and disrupted colonial rule across the region. The occupation was harsh and costly, and it also accelerated political change. After the war, independence movements gained strength, and Indonesia’s struggle for sovereignty became one of the major decolonization stories of the postwar era.

January 11 also appears in the history of aviation and exploration. In 1960, the U.S. Navy bathyscaphe Trieste, piloted by Don Walsh and Jacques Piccard, reached the Challenger Deep in the Mariana Trench, the deepest known point in the ocean. The dive showed that humans and instruments could survive extreme pressure and cold in the deep sea. While the mission was brief, it expanded scientific curiosity about the ocean’s least understood environments and helped inspire later deep-sea research technologies, from improved submersibles to modern remote-operated vehicles.

Culture and media have their own milestones on this date. In 1964, the Beatles’ single “I Want to Hold Your Hand” reached number one on the U.S. charts, a key moment in the “British Invasion.” The song’s success signaled a wider shift in popular music and youth culture, as rock and pop became more globally interconnected through radio, television, and touring. It also showed how quickly a cultural phenomenon could cross borders in the age of mass media.

Sports history adds another layer. On January 11, 1982, the San Francisco 49ers’ “The Catch”—a late touchdown reception by Dwight Clark from Joe Montana against the Dallas Cowboys—helped send the team to the Super Bowl and became one of the NFL’s most replayed moments. It mattered not only as a dramatic finish, but because it marked a changing of the guard in American football, with the 49ers beginning a long period of success and a new style of offense gaining attention.

Notable people born on January 11 span science, leadership, and the arts. In 1755, Alexander Hamilton was born in the Caribbean and later became one of the most influential figures in the early United States. As the first U.S. Secretary of the Treasury, he helped design financial systems that shaped the country’s credit, banking, and federal authority. His ideas sparked debate in his own time and continued to influence how modern states manage public finance.

In 1842, William James was born in New York and became a major figure in psychology and philosophy. He helped develop pragmatism and wrote influential work on how people think, feel, and form beliefs. His approach pushed psychology toward studying real human experience rather than only abstract theory, and his writing helped make the field more accessible to wider audiences.

In 1935, Ghita Nørby was born in Denmark and became one of Scandinavia’s best-known actresses, with a long career in film, television, and theater. Her work reflects the strength of Nordic performing arts and the region’s influence on European cinema, especially through character-driven storytelling.

Several notable deaths on January 11 also left deep marks on history. In 1966, Lal Bahadur Shastri, India’s second prime minister, died in Tashkent shortly after signing an agreement intended to ease tensions following the Indo-Pakistani War of 1965. He was remembered for his leadership during a difficult period and for promoting policies aimed at food security, including support for agricultural reforms that would later be associated with the Green Revolution in India.

In 2007, Robert Anton Wilson died in the United States. He was known for his unconventional essays and fiction, including The Illuminatus! Trilogy (co-written with Robert Shea). While not a mainstream political figure or academic, his work influenced counterculture writing and encouraged readers to question assumptions, explore media narratives, and think about how belief systems form.

Taken together, January 10 and 11 show how human history is built from very different kinds of turning points.
