Black Tuesday Stock Market Crash Begins Great Depression

The Roaring Twenties had fueled speculative investment in U.S. stocks, with prices detached from economic fundamentals amid rising unemployment, agricultural woes, and overproduction. After earlier warnings and a sharp drop on Black Thursday, panic selling intensified on October 29, 1929, as over 16 million shares changed hands on the New York Stock Exchange, erasing billions in value and leaving the ticker tape hours behind. Leading bankers attempted support but could not stem the tide, which continued for days and wiped out fortunes built on margin buying. The crash shattered public confidence in the financial system and exposed vulnerabilities in unregulated markets. Immediate effects included bank runs and business failures that rippled across the industrialized world.

Clyde Tombaugh Discovers Pluto at Lowell Observatory

Astronomers in the early 20th century suspected an undiscovered planet beyond Neptune based on irregularities in the orbits of Uranus and Neptune, leading Percival Lowell to initiate a search for “Planet X” at his observatory in Flagstaff, Arizona. After Lowell’s death, the search continued with improved photographic techniques. On February 18, 1930, 24-year-old Clyde Tombaugh, working as an assistant, identified a moving object on photographic plates taken weeks earlier by comparing images with a blink comparator. Confirmation followed through additional observations, and the discovery was publicly announced in March. The tiny body, later named Pluto, expanded knowledge of the solar system’s outer reaches. Tombaugh’s methodical approach succeeded where prior efforts had failed.

Roosevelt and others present. Completed in just over a year, it stood as the world's tallest building at the time. The opening drew massive public attention despite the era's challenges.

Joan Alexandra Molinsky, later known by the stage name Joan Rivers, was born on June 8, 1933, in Brooklyn, New York City. She worked in small clubs and writing jobs before a 1965 appearance on The Tonight Show Starring Johnny Carson brought national attention.

United States Establishes Relations with Soviet Union

Following the 1917 Bolshevik Revolution, the United States had refused to recognize the Soviet government, citing ideological opposition and unpaid tsarist debts. By 1933, amid the Great Depression and rising threats from Nazi Germany and Imperial Japan, President Franklin D. Roosevelt sought to expand trade opportunities and counterbalance emerging powers. On November 16, 1933, the U.S. and USSR formally established diplomatic relations through an exchange of notes between Roosevelt and Soviet Foreign Minister Maxim Litvinov. The agreement included Soviet promises regarding religious freedoms for Americans in the USSR and settlement of certain financial claims. This step normalized ties after 16 years of non-recognition and opened avenues for economic and strategic cooperation.

Twenty-First Amendment Ends National Prohibition

The Eighteenth Amendment had banned the manufacture, sale, and transportation of alcohol across the United States since 1920, fueling organized crime, speakeasies, and widespread public discontent during the Roaring Twenties and Great Depression. In February 1933 Congress proposed the Twenty-First Amendment to repeal the ban, uniquely requiring ratification by state conventions rather than legislatures. On December 5 Utah became the thirty-sixth state to approve it, meeting the three-fourths threshold; Pennsylvania and Ohio had ratified earlier that day. Acting Secretary of State William Phillips certified the amendment at approximately 5:32 p.m. EST, and President Franklin D. Roosevelt quickly issued a proclamation ending national Prohibition. The repeal immediately allowed legal alcohol sales in most states and generated new tax revenue while diminishing...

Great New England Hurricane Devastates Region

In September 1938, a powerful hurricane formed off the coast of Africa and raced northward along the U.S. East Coast with little warning, as forecasting technology and communication were limited during the Great Depression era. The storm, later known as the Long Island Express, intensified rapidly and made landfall as a Category 3 hurricane on Long Island, New York, on September 21, with sustained winds exceeding 115 mph and a forward speed that amplified its destructive power. It then struck Connecticut and swept through southern New England, generating massive storm surges, flooding, and winds that toppled trees, destroyed homes, and sank ships.

Wells' novel into a realistic news-bulletin format for their Halloween episode. The program aired on CBS on October 30, 1938, simulating reports of a Martian invasion beginning in New Jersey. Some listeners who tuned in late mistook the dramatization for actual events, leading to scattered reports of panic, phone calls to authorities, and minor disruptions. Welles later apologized, and the incident became a landmark in broadcasting history.
