The horrors of modern warfare were on full view in 1915, the second year of World War I. A German U-boat sank the passenger liner Lusitania off Ireland, German zeppelins bombed London, the French developed a fighter plane that could fire precisely timed machine-gun bullets through its propeller, and German troops unleashed poison gas for the first time on the battlefield. In America, meanwhile, a young Boston Red Sox pitcher named Babe Ruth clubbed his first major-league homer.

1975

In 1954, a year of breakthroughs, the first successful polio vaccine rolled out and the U.S. Supreme Court ruled school segregation unconstitutional. In England, Roger Bannister became the first man to run a mile in under four minutes. Two pop-culture titans, movie star Marilyn Monroe and baseball slugger Joe DiMaggio, tied the knot. And Bill Haley and His Comets released “Rock Around the Clock,” one of the earliest and most successful rock ‘n’ roll records.

1961

With months to spare, the Apollo 11 astronauts fulfilled late President John F. Kennedy’s 1961 goal of landing a man on the moon by the end of the decade. Back on earth, 1969 was also the year of the Woodstock music festival, the Stonewall riots for gay rights and the Tate-LaBianca murders by followers of Charles Manson. "Butch Cassidy and the Sundance Kid" and "The Love Bug" topped Hollywood box office, and a movie ticket cost about $1.50.	

1969

World War II ended in 1945, after Germany surrendered in May and Japan capitulated in August, days after powerful new atomic bombs exploded over Hiroshima and Nagasaki. Two months later, 29 nations ratified a charter to form the United Nations. Writer George Orwell coined the term “cold war,” predicting icy relations between the U.S. and U.S.S.R., while popular songs like “Ac-Cent-Tchu-Ate the Positive" and “Sentimental Journey” reflected the stateside mood as some 4 million G.I.s returned home.

1945

In 1865, the American Civil War came to an end, President Lincoln was assassinated and the 13th amendment was ratified, abolishing slavery in the U.S. The Secret Service came into being, originally created to prevent widespread counterfeiting that plagued the financial system. Elsewhere in the world, rebels in the Dominican Republic forced out Spanish occupiers to restore their country’s independence, and in England, Lewis Carroll published “Alice’s Adventures in Wonderland.”
