September 24 in History

Eight days after proposing the Bill of Rights, the first United States Congress took on an equally foundational task: building a court system from scratch. On September 24, 1789, President George Washington signed the Judiciary Act, creating the federal court structure that still operates today and establishing the office of Attorney General. The Constitution had provided only the barest outline for a judiciary. Article III called for "one Supreme Court" and "such inferior courts as the Congress may from time to time ordain and establish," leaving almost every practical detail to lawmakers. Senator Oliver Ellsworth of Connecticut, a future Chief Justice, drafted the bill that filled in the blanks. The act established a Supreme Court with one Chief Justice and five Associate Justices, along with thirteen district courts and three circuit courts covering the eastern, middle, and southern regions of the country. Federal judges received lifetime appointments, insulating them from political pressure. The act also created the position of Attorney General, though the office initially had no staff and a salary so modest that the first holder, Edmund Randolph, continued his private law practice to pay his bills. Section 25 proved the most consequential and controversial provision. It granted the Supreme Court authority to review and overturn state court decisions that conflicted with federal law or the Constitution. Anti-Federalists attacked this clause as a dangerous centralization of power, and states' rights advocates would challenge it repeatedly for the next seven decades. But Section 25 gave the federal judiciary the teeth it needed to enforce constitutional supremacy, a power that Chief Justice John Marshall would use to transformative effect in cases like Marbury v. Madison and McCulloch v. Maryland. The Judiciary Act has been amended dozens of times, the number of Supreme Court justices has changed seven times, and the lower court system has been reorganized repeatedly. But the essential framework Ellsworth designed in 1789 remains the skeleton of American federal justice.

Jay Gould and Jim Fisk tried to buy all the gold in America. On September 24, 1869, their scheme collapsed in a matter of minutes, triggering a financial panic that ruined thousands of investors and tarnished the Grant administration before it was a year old. The plan was audacious in its simplicity. The U.S. Treasury held large gold reserves, and the government's policy of selling gold periodically kept prices stable. If Gould and Fisk could corner the private gold market while convincing President Ulysses S. Grant to halt government sales, they could drive the price as high as they wanted and sell at enormous profit. Gould cultivated access to the White House through Abel Corbin, Grant's brother-in-law, and planted Daniel Butterfield as an inside man at the Treasury. Through the summer of 1869, Gould quietly accumulated gold contracts while Fisk loudly bought on the open market, pushing the price steadily upward. Stocks fell as gold rose, and legitimate businesses dependent on stable currency markets began to panic. By the morning of September 24, gold had surged to $162 an ounce, a 30 percent premium over its price when Grant took office. Trading floors in New York were scenes of hysteria, with brokers screaming orders and grown men weeping as their positions collapsed. Grant, finally grasping the conspiracy, ordered the Treasury to sell $4 million in gold. The price crashed to $133 within fifteen minutes. The carnage was widespread. Fortunes evaporated instantly. Several brokerages failed. Foreign trade seized up for weeks as the currency markets convulsed. Gould had quietly sold his positions before the crash and escaped with his profits intact. Fisk simply repudiated his contracts, using hired thugs and corrupt judges to avoid paying his debts. A congressional investigation exposed the scheme but produced no criminal charges. Grant was personally exonerated but politically damaged by his association with Corbin and the speculators. Black Friday demonstrated how vulnerable the post-Civil War financial system was to manipulation and became a lasting cautionary tale about the dangers of unregulated markets.

Fifty-one years after the bombings of Hiroshima and Nagasaki, representatives from 71 nations gathered at the United Nations headquarters in New York on September 24, 1996, to sign the Comprehensive Nuclear-Test-Ban Treaty, the most ambitious arms control agreement since the dawn of the atomic age. President Bill Clinton was the first to add his signature, calling it "the longest-sought, hardest-fought prize in arms control history." The road to the CTBT began in the radioactive fallout of the early Cold War. Between 1945 and 1996, the world's nuclear powers conducted over 2,000 test explosions, contaminating vast stretches of the Pacific, Central Asia, and the American Southwest. Public alarm over atmospheric testing, particularly after the 1954 Castle Bravo test showered a Japanese fishing vessel with lethal fallout, led to the 1963 Partial Test Ban Treaty, which pushed testing underground but did not stop it. Negotiations for a comprehensive ban stalled for decades as the nuclear powers insisted they needed continued testing to maintain their arsenals. The end of the Cold War broke the impasse. France and China conducted their final tests in 1996, and the treaty opened for signature that September. By the end of the first day, 71 countries had signed; within two years, the number exceeded 150. The treaty established the International Monitoring System, a global network of 337 seismological, hydroacoustic, infrasound, and radionuclide stations capable of detecting even small underground explosions anywhere on the planet. The system has proven remarkably effective, detecting all of North Korea's nuclear tests within minutes. The CTBT's weakness lies in its ratification requirements. The treaty cannot formally enter into force until 44 specific nations with nuclear technology ratify it. As of 2025, eight of those nations have not done so, including the United States, China, and Israel. The U.S. Senate rejected ratification in 1999, and no subsequent administration has resubmitted it. Despite never officially taking effect, the CTBT has established a powerful global norm. No country besides North Korea has conducted a nuclear test explosion since 1998.

Massive forest fires across Canada and New England pumped so much smoke into the upper atmosphere in September 1950 that the sun vanished behind a dark haze and the moon turned blue as far away as Europe. The fires burned across Alberta, British Columbia, and several northeastern U.S. states simultaneously, consuming millions of acres of timber in conditions of extreme drought. Smoke particles rose to altitudes of over twenty thousand feet and were carried eastward by upper-level winds, creating optical effects visible across the Atlantic Ocean. The blue moon phenomenon occurred because smoke particles approximately one micrometer in diameter scattered red light more effectively than blue, reversing the normal atmospheric scattering pattern. Cities across New England reported midday darkness, with streetlights turning on automatically and residents reporting an eerie, apocalyptic atmosphere. Baseball games were played under floodlights at noon. The phenomenon lasted for several days and was documented by atmospheric scientists who recognized it as evidence that large-scale wildfires could alter atmospheric optics across an entire hemisphere. The fires were the product of a severe drought that had dried out forests across the northern latitudes, combined with logging practices that left slash and debris on the forest floor. The Canadian fires alone burned over three million acres. The event demonstrated for the first time how biomass burning could produce hemispheric-scale atmospheric effects, a preview of the climate disruptions that fire seasons would increasingly produce as global temperatures rose in subsequent decades. The phrase "once in a blue moon" predates this event, but the 1950 fires provided one of its most literal demonstrations.

Before the World Wide Web, before AOL, before most Americans had ever heard the word "modem," there was CompuServe. On September 24, 1979, the Columbus, Ohio-based company launched MicroNET, the first commercial online service available to consumers with personal computers. For the first time, ordinary people could send electronic mail, read news, and access databases from their homes. CompuServe had started in 1969 as a time-sharing computer service for businesses, renting out excess mainframe capacity to corporate clients. When personal computers began appearing in the late 1970s, company executive Jeff Wilkins recognized that those same mainframes sat mostly idle during evenings and weekends. MicroNET, later renamed the CompuServe Information Service, sold that spare capacity to home users for $5 per hour during off-peak times. The early service was primitive by modern standards. Users connected through acoustic couplers at 300 baud, roughly 30 characters per second. The interface was entirely text-based, and navigating required memorizing page numbers or typing commands. But the appeal was immediate. CompuServe's forums, called SIGs (Special Interest Groups), became the first large-scale online communities, connecting hobbyists, professionals, and enthusiasts across geographic boundaries years before anyone coined the term "social media." By the mid-1980s, CompuServe had grown to over 600,000 subscribers and offered services including stock quotes, airline reservations, shopping, and the CB Simulator, an early form of online chat. The company introduced the GIF image format in 1987, a file type that would outlast CompuServe itself. At its peak in the early 1990s, the service claimed over 3 million subscribers worldwide. The arrival of the graphical World Wide Web and America Online's aggressive marketing campaigns eroded CompuServe's subscriber base throughout the 1990s. AOL acquired the service in 1997. But for nearly two decades, CompuServe proved that millions of people would pay to communicate and access information through networked computers, validating the commercial model that the entire modern internet economy rests upon.
