Helen M Kaiser was 10 years old when The Wright brothers make their first attempt to fly with the Wright Flyer at Kitty Hawk, North Carolina. The Wright brothers, Orville and Wilbur, were two American aviators, engineers, inventors, and aviation pioneers who are generally credited with inventing, building, and flying the world's first successful airplane. They made the first controlled, sustained flight of a powered, heavier-than-air aircraft on December 17, 1903, four miles south of Kitty Hawk, North Carolina. In 1904–05 the brothers developed their flying machine into the first practical fixed-wing aircraft. Although not the first to build experimental aircraft, the Wright brothers were the first to invent aircraft controls that made fixed-wing powered flight possible.
Helen M Kaiser was 21 years old when Archduke Franz Ferdinand and his wife, Sophie, Duchess of Hohenberg, were assassinated by a Yugoslav nationalist named Gavrilo Princip in Sarajevo, sparking the outbreak of World War I. Archduke Franz Ferdinand, Archduke of Austria-Este was a member of the imperial Habsburg dynasty, and from 1896 until his death the heir presumptive (Thronfolger) to the Austro-Hungarian throne.

Nicknamed "The Bambino" and "The Sultan of Swat", he began his MLB career as a stellar left-handed pitcher for the Boston Red Sox, but achieved his greatest fame as a slugging outfielder for the New York Yankees. Ruth established many MLB batting records, including career home runs (714), runs batted in (RBIs) (2,213), bases on balls (2,062), slugging percentage (.690), and on-base plus slugging (OPS) (1.164); the latter two still stand as of 2018. Ruth is regarded as one of the greatest sports heroes in American culture and is considered by many to be the greatest baseball player of all time. In 1936, Ruth was elected into the Baseball Hall of Fame as one of its "first five" inaugural members.

Helen M Kaiser was 48 years old when World War II: The Imperial Japanese Navy made a surprise attack on Pearl Harbor in Hawaii, intending to neutralize the United States Pacific Fleet from influencing the war Japan was planning to wage in Southeast Asia. World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945, although conflicts reflecting the ideological clash between what would become the Allied and Axis blocs began earlier. The vast majority of the world's countries—including all of the great powers—eventually formed two opposing military alliances: the Allies and the Axis. It was the most global war in history; it directly involved more than 100 million people from over 30 countries. In a state of total war, the major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. World War II was the deadliest conflict in human history, marked by 50 to 85 million fatalities, most of whom were civilians in the Soviet Union and China. It included massacres, the genocide of the Holocaust, strategic bombing, premeditated death from starvation and disease and the only use of nuclear weapons in war.
Helen M Kaiser was 60 years old when Jonas Salk announced the successful test of his polio vaccine on a small group of adults and children (vaccination pictured). Jonas Edward Salk was an American medical researcher and virologist. He discovered and developed one of the first successful polio vaccines.

Two years later he was granted a fellowship at the University of Michigan, where he would study flu viruses with his mentor Thomas Francis, Jr.
Helen M Kaiser was 76 years old when During the Apollo 11 mission, Neil Armstrong and Buzz Aldrin became the first humans to walk on the Moon. Apollo 11 was the spaceflight that landed the first two people on the Moon. Mission commander Neil Armstrong and pilot Buzz Aldrin, both American, landed the lunar module Eagle on July 20, 1969, at 20:17 UTC. Armstrong became the first person to step onto the lunar surface six hours after landing on July 21 at 02:56:15 UTC; Aldrin joined him about 20 minutes later. They spent about two and a quarter hours together outside the spacecraft, and collected 47.5 pounds (21.5 kg) of lunar material to bring back to Earth. Michael Collins piloted the command module Columbia alone in lunar orbit while they were on the Moon's surface. Armstrong and Aldrin spent 21.5 hours on the lunar surface before rejoining Columbia in lunar orbit.
Helen M Kaiser was 80 years old when Vietnam War: The last United States combat soldiers leave South Vietnam. The Vietnam War, also known as the Second Indochina War, and in Vietnam as the Resistance War Against America or simply the American War, was a conflict that occurred in Vietnam, Laos, and Cambodia from 1 November 1955 to the fall of Saigon on 30 April 1975. It was the second of the Indochina Wars and was officially fought between North Vietnam and the government of South Vietnam. The North Vietnamese army was supported by the Soviet Union, China, and other communist allies; the South Vietnamese army was supported by the United States, South Korea, Australia, Thailand and other anti-communist allies. The war is considered a Cold War-era proxy war by some US perspectives. The majority of Americans believe the war was unjustified. The war would last roughly 19 years and would also form the Laotian Civil War as well as the Cambodian Civil War, which also saw all three countries become communist states in 1975.
