In 1907, in the year that Karl Ein was born, radiometric dating, a recently discovered technology that could date rocks, found that the earth was 2.2 billion years old which was dramatically older than previously thought. Later refinements and advancements in science would date the age of the earth at over 4.5 billion years.

In 1921, he was merely 14 years old when on March 4, Warren G. Harding became President. Previously a U.S. Senator, Lieutenant Governor, and Ohio State Senator, Harding was a popular President. But many scandals plagued his short administration (he died in office after 2 and a half years), including the revelations of one of his mistresses and the Teapot Dome scandal. Historically, Harding is rated as one of the worst Presidents.

In 1937, when he was 30 years old, on May 28th, the San Francisco Golden Gate Bridge opened to cars. Taking 5 years to build, the 4,200-foot-long suspension bridge was an engineering marvel of its time - 11 men died during construction. The "international orange" color was chosen because it resisted rust and fading. To the present, it is the symbol of the City that is known throughout the world.

In 1945, Karl was 38 years old when on August 15th, Imperial Japan announced its surrender. On September 2nd, a formal agreement of surrender was signed. Japan and nine other states signed the Japanese Instrument of Surrender in Tokyo Bay, calling for the return of all Allied prisoners of war and subordinating the authority of the emperor and the Japanese government to the Supreme Commander for the Allied Powers. VJ (Victory in Japan) Day was celebrated in the United States on August 14th and 15th. World War II was over.

In 1975, in the year of Karl Ein's passing, in January, Popular Mechanics featured the Altair 8800 on it's cover. The Altair home computer kit allowed consumers to build and program their own personal computers. Thousands were sold in the first month.
