Sir James Young Simpson first experimented with chloroform on November 4, 1847, observing its ability to induce insensibility to pain. His successful trials on himself and colleagues marked a breakthrough in anesthetic medicine. Before chloroform, surgical procedures were performed without effective pain control, causing immense suffering. Simpson’s work paved the way for safer and more humane surgeries worldwide. Within months, chloroform was adopted in hospitals across Europe and North America. Its use soon extended to obstetrics, significantly reducing maternal mortality. Simpson’s discovery also sparked further research into anesthetic agents. Chloroform remained in use until newer, safer anesthetics were developed.

On November 4, 1922, British archaeologist Howard Carter and his team uncovered the entrance to the nearly intact tomb of Pharaoh Tutankhamun in Egypt's Valley of the Kings. The discovery came after years of meticulous excavation and financial support from Lord Carnarvon. Carter's careful removal of debris revealed a sealed doorway bearing the pharaoh's name in hieroglyphs. Inside, the team found a wealth of artifacts, including the iconic golden death mask and elaborately decorated burial chambers. This find captivated the world and sparked a renewed fascination with ancient Egyptian civilization. The excavation would continue for nearly a decade, reshaping archaeological methods and our understanding of the New Kingdom period.

On November 4, 1952, President Harry S. Truman authorized the formation of the National Security Agency (NSA). The NSA was tasked with collecting and analyzing foreign communications and signals intelligence. It consolidated various cryptologic functions previously scattered across military and civilian agencies. Operating in secrecy, the NSA played a vital role in Cold War intelligence and national security. Its establishment laid the foundation for modern electronic surveillance and cybersecurity efforts. Over the decades, the agency's activities have sparked debates over privacy, civil liberties, and government transparency.

On November 4, 1960, primatologist Jane Goodall witnessed chimpanzees in the Kasakela community fashioning and using tools to fish termites. Her meticulous fieldwork at Gombe Stream National Park challenged the belief that tool use was uniquely human. This observation marked a turning point in primatology and the study of animal cognition. Goodall's findings demonstrated complex problem-solving and cultural transmission among chimpanzees. Her research paved the way for ethical reforms in wildlife conservation and research practices. Today, Goodall's work remains foundational to primate studies and environmental advocacy.

On November 4, 1962, the United States wrapped up Operation Fishbowl, its final series of high-altitude nuclear detonations over the Pacific Ocean. These tests, launched via rockets and missiles, aimed to study the effects of nuclear explosions in the near-space environment. Mounting concerns over radioactive fallout and global public health spurred calls for a ban on atmospheric testing. The conclusion of Operation Fishbowl underscored the urgency of arms control negotiations. This event directly paved the way for the signing of the 1963 Partial Nuclear Test Ban Treaty, prohibiting further above-ground nuclear tests.
