U.S. flag raised on Iwo Jima. During the bloody Battle for Iwo Jima, U.S. Marines from the 3rd Platoon, E Company, 2nd Battalion, 28th Regiment of the 5th Division take the crest of Mount Suribachi, the island's highest peak and most strategic position, and raise the U.S. flag. Marine photographer Louis Lowery was with them and recorded the event. American soldiers fighting for control of Suribachi's slopes cheered the raising of the flag, and several hours later more Marines headed up to the crest with a larger flag. Joe Rosenthal, a photographer with the Associated Press, met them along the way and recorded the raising of the second flag along with a Marine still photographer and a motion-picture cameraman.
Feb 24, 1836
Alamo defenders call for help. On this day in 1836, in San Antonio, Texas, Colonel William Travis issues a call for help on behalf of the Texan troops defending the Alamo, an old Spanish mission and fortress under attack by the Mexican army. A native of Alabama, Travis moved to the Mexican state of Texas in 1831. He soon became a leader of the growing movement to overthrow the Mexican government and establish an independent Texan republic. When the Texas revolution began in 1835, Travis became a lieutenant-colonel in the revolutionary army and was given command of troops in the recently captured city of San Antonio de Bexar (now San Antonio). On February 23, 1836, a large Mexican force commanded by General Antonio Lopez de Santa Ana arrived suddenly in San Antonio. Travis and his troops took shelter in the Alamo, where they were soon joined by a volunteer force led by Colonel James Bowie.
Feb 25, 1964
Clay knocks out Liston. On February 25, 1964, 22-year-old Cassius Clay shocks the odds-makers by dethroning world heavyweight boxing champ Sonny Liston in a seventh-round technical knockout. The dreaded Liston, who had twice demolished former champ Floyd Patterson in one round, was an 8-to-1 favorite. However, Clay predicted victory, boasting that he would "float like a butterfly, sting like a bee" and knock out Liston in the eighth round. The fleet-footed and loquacious youngster needed less time to make good on his claim--Liston, complaining of an injured shoulder, failed to answer the seventh-round bell. A few moments later, a new heavyweight champion was proclaimed. Cassius Marcellus Clay Jr. was born in Louisville, Kentucky, in 1942. He started boxing when he was 12 and by age 18 had amassed a record of over 100 wins in amateur competition. In 1959, he won the International Golden Gloves heavyweight title and in 1960 a gold medal in the light heavyweight category at the Summer Olympic Games in Rome. Clay turned professional after the Olympics and went undefeated in his first 19 bouts, earning him the right to challenge Sonny Liston, who had defeated Floyd Patterson in 1962 to win the heavyweight title.
Feb 26, 1919
Two national parks preserved, 10 years apart.On this day in history, two national parks were established in the United States 10 years apart--the Grand Canyon in 1919 and the Grand Tetons in 1929. Located in northwestern Arizona, the Grand Canyon is the product of millions of years of excavation by the mighty Colorado River. The chasm is exceptionally deep, dropping more than a mile into the earth, and is 15 miles across at its widest point. The canyon is home to more than 1,500 plant species and over 500 animal species, many of them endangered or unique to the area, and it's steep, multi-colored walls tell the story of 2 billion years of Earth's history. In 1540, members of an expedition sent by the Spanish explorer Coronado became the first Europeans to discover the canyon, though because of its remoteness the area was not further explored until 300 years later. American geologist John Wesley Powell, who popularized the term "Grand Canyon" in the 1870s, became the first person to journey the entire length of the gorge in 1869. The harrowing voyage was made in four rowboats.
Feb 27, 1827
New Orleanians take to the streets for Mardi Gras. On this day in 1827, a group of masked and costumed students dance through the streets of New Orleans, Louisiana, marking the beginning of the city's famous Mardi Gras celebrations. The celebration of Carnival--or the weeks between Twelfth Night on January 6 and Ash Wednesday, the beginning of the Christian period of Lent--spread from Rome across Europe and later to the Americas. Nowhere in the United States is Carnival celebrated as grandly as in New Orleans, famous for its over-the-top parades and parties for Mardi Gras (or Fat Tuesday), the last day of the Carnival season. Though early French settlers brought the tradition of Mardi Gras to Louisiana at the end of the 17th century, Spanish governors of the province later banned the celebrations. After Louisiana became part of the United States in 1803, New Orleanians managed to convince the city council to lift the ban on wearing masks and partying in the streets. The city's new Mardi Gras tradition began in 1827 when the group of students, inspired by their experiences studying in Paris, donned masks and jester costumes and staged their own Fat Tuesday festivities.
Feb 28, 1953
Watson and Crick discover chemical structure of DNA. On this day in 1953, Cambridge University scientists James D. Watson and Frances H.C. Crick announce that they have determined the double-helix structure of DNA, the molecule containing human genes. Though DNA--short for deoxyribonucleic acid--was discovered in 1869, its crucial role in determining genetic inheritance wasn't demonstrated until 1943. In the early 1950s, Watson and Crick were only two of many scientists working on figuring out the structure of DNA. California chemist Linus Pauling suggested an incorrect model at the beginning of 1953, prompting Watson and Crick to try and beat Pauling at his own game. On the morning of February 28, they determined that the structure of DNA was a double-helix polymer, or a spiral of two DNA strands, each containing a long chain of monomer nucleotides, wound around each other. According to their findings, DNA replicated itself by separating into individual strands, each of which became the template for a new double helix. In his best-selling book, The Double Helix (1968), Watson later claimed that Crick announced the discovery by walking into the nearby Eagle Pub and blurting out that "we had found the secret of life." The truth wasn’t that far off, as Watson and Crick had solved a fundamental mystery of science--how it was possible for genetic instructions to be held inside organisms and passed from generation to generation.
Mar 01, 1932
Lindbergh baby kidnapped. On this day in 1932, in a crime that captured the attention of the entire nation, Charles Lindbergh III, the 20-month-old son of aviation hero Charles Lindbergh, is kidnapped from the family's new mansion in Hopewell, New Jersey. Lindbergh, who became an international celebrity when he flew the first solo flight across the Atlantic Ocean in 1927, and his wife Anne discovered a ransom note demanding $50,000 in their son's empty room. The kidnapper used a ladder to climb up to the open second-floor window and left muddy footprints in the room. The Lindberghs were inundated by offers of assistance and false clues. Even Al Capone offered his help from prison. For three days, investigators found nothing and there was no further word from the kidnappers. Then, a new letter showed up, this time demanding $70,000.
