On July 2, 1865, William Booth and his wife, Catherine Booth, founded the Christian Mission in London's East End. Their goal was to bring practical help and Christian teaching to people struggling with poverty and hardship. Inspired by military organization, Booth introduced ranks such as officers and recruits, believing discipline and structure would strengthen the movement. Women were given leadership roles alongside men, an uncommon practice for the time.
The Christian Mission quickly expanded its work into some of London's poorest communities, opening soup kitchens and offering both physical assistance and spiritual support. Its energetic public preaching and unusual methods were not welcomed by everyone, and members frequently faced hostility, fines, and even imprisonment as authorities attempted to curb their activities.
In 1878, the organization adopted the name the The Salvation Army, and two years later established its first branch in the United States. During the Great Depression and both World Wars, the organization became widely respected for providing food, shelter, and support to civilians and military personnel alike. Today, the Salvation Army operates in more than 130 countries, delivering disaster relief, rehabilitation programs, community services, hospitals, thrift stores, and other charitable initiatives, supported through donations and the proceeds of its retail operations.
On October 1, 1908, Ford completed the first production Model T at its Piquette Avenue plant in Detroit, launching an automobile that would dramatically change personal transportation. Cars were still beyond the reach of most families, but Henry Ford intended the Model T to be durable, simple to operate and affordable enough for ordinary Americans. Powered by a four-cylinder engine producing about 20 horsepower, the lightweight car was capable of roughly 40 mph and proved particularly well suited to the rough and frequently unpaved roads of the period.
Ford continually refined the way the Model T was manufactured. Standardized interchangeable parts simplified construction, while the introduction of the moving assembly line dramatically reduced production time and costs. Those efficiencies allowed Ford to lower the car's price as production increased, helping transform automobile ownership from a privilege of the wealthy into something attainable for millions of households. By the 1920s, Model Ts were everywhere, earning affectionate nicknames including the "Tin Lizzie" and becoming an enduring symbol of America's rapidly changing transportation landscape.
Eventually, however, motorists began expecting more comfort, styling and performance than the increasingly old-fashioned Model T offered. Ford ended production on May 26, 1927, after manufacturing more than 15 million examples during its remarkable run. Its influence lasted considerably longer: mass-production techniques perfected during the Model T era reshaped manufacturing around the world, while affordable automobiles permanently changed where Americans could live, work and travel. The Model T didn't invent the automobile, but it played an enormous part in putting America behind the wheel.
On October 6, 1866, brothers John and Simeon Reno carried out what is widely regarded as the first robbery of a moving train in the United States. The pair targeted an Ohio and Mississippi Railway train near Seymour in Jackson County, Indiana, escaping with approximately $13,000. Railroad theft was not new, but earlier criminals generally burglarized trains while they were stopped in stations, depots or rail yards. The Reno brothers demonstrated something considerably bolder: stop a train in an isolated location, rob it and disappear before authorities could respond.
The idea quickly attracted imitators, particularly as railroads expanded across the American West. Trains regularly transported payrolls, currency, gold, silver and other valuables through vast stretches of sparsely populated territory, making them tempting targets for outlaws. Remote landscapes provided plenty of places to halt a train and just as many places to hide afterward. By the late 19th century, train robbery had become one of the enduring symbols of the Wild West, with gangs such as Butch Cassidy's Wild Bunch becoming especially notorious for attacking railroad shipments.
Railroad companies eventually responded by making the occupation considerably less appealing. Valuable cargo was placed inside stronger safes, armed guards accompanied important shipments, and some railroads developed special arrangements allowing guards and horses to travel aboard trains so pursuing posses could get underway quickly. As security improved and law enforcement became more effective, robbing a train became increasingly dangerous. What the Reno brothers had helped introduce as an ingenious criminal opportunity gradually became a very good way for an outlaw to discover that the railroad had brought considerably more firepower than expected.

On October 7, 1913, Henry Ford's Highland Park plant in Michigan reached a major milestone when the Model T chassis was placed on a continuously moving assembly line. Rather than having workers move around a stationary automobile, a rope and motor pulled the chassis past employees positioned to perform specific tasks. Ford had already experimented successfully with moving production for magnetos, engines and transmissions, and applying the method to the chassis completed the transformation of the Model T production process. The results were dramatic: assembly required fewer working hours, and continued refinements eventually reduced the time needed to build a chassis to about 93 minutes.
Ford's goal had always been to manufacture an automobile that ordinary Americans could afford. When the Model T debuted in 1908, its $850 price was considerably less than many competing automobiles but still beyond the means of much of the population. Ford realized that greater production efficiency could drive prices lower. His engineers drew partly upon methods used in nineteenth-century meatpacking plants, where overhead systems moved carcasses from one specialized worker to another. Ford adapted that principle to manufacturing, dividing complicated jobs into smaller, repetitive operations while the product itself traveled through the factory.
The impact was enormous. By 1916, the Model T's price had dropped to about $360 while sales had risen dramatically, and Ford eventually became capable of producing a Model T approximately every 24 seconds. More than 15 million were manufactured before production ended in 1927. The Model T helped put automobile ownership within reach of millions of people, while Ford's moving assembly line demonstrated a system of mass production that manufacturers around the world would adopt and refine. The automobile changed how Americans traveled; the factory that built it helped change how the industrial world worked.
On October 7, 1943, Rear Admiral Shigematsu Sakaibara, commander of the Japanese garrison on Wake Island, ordered the execution of 98 American prisoners of war who had remained on the island as forced laborers. Sakaibara later claimed that the prisoners had attempted to communicate by radio with American forces. The men were blindfolded and killed by Japanese personnel in what became known as the Wake Island massacre.
Japanese forces had captured Wake Island in December 1941 after an earlier invasion attempt was repelled by its American defenders. Most surviving American military personnel and civilian workers were subsequently transported to prisoner-of-war camps elsewhere in the Japanese Empire, but 98 civilian prisoners were retained on Wake to perform construction and other forced labor. As the Pacific War progressed, American aircraft periodically bombed the strategically isolated island, while U.S. forces bypassed it rather than attempting another amphibious invasion.
Following an especially heavy American air attack in October 1943, Sakaibara ordered the remaining prisoners killed. One prisoner initially escaped the execution and reportedly carved a message into a coral rock recording the fate of the group before he was recaptured and personally killed by Sakaibara. After Japan surrendered in 1945, the massacre was investigated as a war crime. Sakaibara was tried by a U.S. military commission on Guam, convicted and executed in 1947.
On October 7, 1960, CBS premiered Route 66, a one-hour television drama following two young men traveling across America in a Chevrolet Corvette. Tod Stiles, played by Martin Milner, and Buz Murdock, played by George Maharis, moved from place to place, taking temporary jobs and becoming involved in the lives of the people they encountered. Beneath that straightforward road-trip premise was something considerably more ambitious. Creator and writer Stirling Silliphant envisioned their travels as a continuing search for experience, understanding and personal identity rather than simply an excuse to put two fellows in a very attractive sports car.
Unlike most television dramas of its era, Route 66 was filmed extensively on location rather than relying primarily on Hollywood studio sets. During its four-season run, the production traveled throughout the United States and occasionally beyond it, producing 116 episodes before ending in 1964. The constantly changing locations allowed the writers to explore an unusually broad collection of subjects, including war, addiction, mental illness, religion, racial and social tensions, crime and economic hardship. Its black-and-white photography helped give the series a distinctive, sometimes stark appearance that complemented its generally serious storytelling.
Ironically, Tod and Buz did not spend all that much time traveling on the actual Route 66, the famous highway connecting Chicago with Los Angeles. The historic road nevertheless provided an ideal symbol for a series built around movement, discovery and the changing American landscape. Already celebrated in John Steinbeck's The Grapes of Wrath and Bobby Troup's song "(Get Your Kicks on) Route 66," the highway was firmly established in American popular culture. NBC attempted to revive the television concept in 1993 with another Corvette and another pair of travelers, but the new series lasted only a handful of episodes. The original, meanwhile, remains a fascinating television journey through early-1960s America—with a Corvette that did a remarkably good job of stealing the scenery.
On October 7, 1975, a federal appeals court overturned an order that would have deported former Beatle John Lennon from the United States. Lennon had been living in New York City with Yoko Ono and had become increasingly outspoken about political and social issues, particularly his opposition to the Vietnam War. His activism and associations with prominent antiwar figures attracted the attention of the Nixon administration at a time when the voting age had recently been lowered to 18 and officials were concerned about Lennon's potential influence among younger voters.
Immigration authorities began proceedings against Lennon in 1972, citing his 1968 conviction in Britain for possession of cannabis. Lennon and his immigration attorney, Leon Wildes, fought the deportation effort for several years, arguing that immigration law was being applied selectively because of Lennon's political activities. On October 7, 1975, the U.S. Court of Appeals for the Second Circuit ruled in Lennon's favor. Judge Irving Kaufman wrote that the courts would not accept selective deportation based on undisclosed political considerations and overturned the order requiring Lennon to leave the country.
The decision ended the most serious threat to Lennon's ability to remain in his adopted home. After years of hearings, appeals and government scrutiny, he was finally granted permanent resident status in 1976 and received his green card. Lennon continued to make his home in New York City, where he lived for the remainder of his life.
On October 7, 2003, California voters recalled Governor Gray Davis and selected actor and businessman Arnold Schwarzenegger as his replacement. The unusual special election followed an intense campaign lasting only a few months and featured a remarkably crowded field of candidates. Schwarzenegger, running as a Republican despite having little conventional political experience, defeated his replacement-election rivals and became California's governor. Official results showed that 55.4 percent of voters supported removing Davis from office. California Secretary of State
Born in Austria in 1947, Schwarzenegger first became internationally famous through bodybuilding, winning major titles including Mr. Universe and Mr. Olympia before establishing himself in the United States. Hollywood eventually provided an even larger stage. After appearances in Stay Hungry and the bodybuilding documentary Pumping Iron, he became an international action star through movies including Conan the Barbarian and The Terminator. Schwarzenegger became a U.S. citizen in 1983 and had previously entered public service as chairman of the President's Council on Physical Fitness and
Sports before announcing his California gubernatorial campaign in 2003.
The recall election itself was unlike almost anything previously seen in California politics. Voters were asked whether Davis should be removed and, separately, which candidate should replace him if the recall succeeded. Schwarzenegger emerged from the enormous replacement field and was sworn into office on November 17, 2003. California Secretary of State He subsequently won a full term in the 2006 election and remained governor until January 2011, after which he returned to acting and other business and public activities. Thus, on October 7, 2003, the man best known for playing the Terminator discovered one role Hollywood had never given him: Governor of California.
