On February 2, 1848, the Treaty of Guadalupe Hidalgo is signed, ending the Mexican-American War in favor of the United States. The Treaty of Guadeloupe Hidalgo added an additional 525,000 square miles to United States territory, including the area that would become the states of Texas, California, Nevada, Utah, New Mexico and Arizona, as well as parts of Colorado and Wyoming. Controversy during and after the war pitted President James K. Polk in a political war against two future presidents: Zachary Taylor and Abraham Lincoln.

On February 2, 1887, Groundhog Day, featuring a rodent meteorologist, is celebrated for the first time at Gobbler’s Knob in Punxsutawney, Pennsylvania. According to tradition, if a groundhog comes out of its hole on this day and sees its shadow, it gets scared and runs back into its burrow, predicting six more weeks of winter weather; no shadow means an early spring.

On February 2, 1913, New York City’s Grand Central Terminal opens for the first time. The transportation hub as we know it today began construction in 1903, but before that 89 E 42nd was home to an older steam train station built in 1879. Even though the station had been updated to deal with an increased volume of commuters coming from suburbs outside the city, a collision between outdated steam trains in 1902 killed 15 people, and made it clear that a more substantial renovation was needed.

Police discover the body of film director William Desmond Taylor in his Los Angeles bungalow. Lieutenant Tom Ziegler responded to a call about a “natural death” at the Alvarado Street home of Taylor. When he arrived they found actors, actresses and studio executives rummaging through the director’s belongings. He also found Taylor lying on the living room floor with a bullet in his back—not exactly suggesting a “natural” death.

In response to Soviet leader Joseph Stalin’s proposal that President Harry S. Truman travel to Russia for a conference, Secretary of State Dean Acheson brusquely rejects the idea as a “political maneuver.” This rather curious exchange was further evidence of the diplomatic sparring between the United States and the Soviet Union that was so characteristic of the early years of the Cold War.

The first U.S. Air Force plane is lost in South Vietnam. The C-123 aircraft crashed while spraying defoliant on a Viet Cong ambush site.

One week after toppling the regime of Ugandan leader Milton Obote, Major General Idi Amin declares himself president of Uganda and chief of the armed forces. Amin, head of the Ugandan army and air force since 1966, seized power while Obote was out of the country.

On February 2, 1979, Sid Vicious, former bassist for the notorious Sex Pistols—and the living embodiment of everything punk rock stood for and against—dies of a heroin overdose in a Greenwich Village apartment. His death likely came as a surprise to very few.

Weeks after California passed a law against cyberstalking, Gary Dellapenta is charged with using the Internet to solicit the rape of a woman who had rejected his advances. (He pleads not guilty.) Dellapenta terrorized a North Hollywood woman by placing ads in her name that claimed she had rape fantasies and provided her address and instructions for disarming her security system. At least six men saw the Internet ads and came to the woman’s home. Many more called with obscene messages.
