In 1898, in the year that John Etheridge Ryan was born, on March 24th, Robert Allison of Pennsylvania became the first person to buy an American-built car. He bought a Winton, which he had seen in an advertisement in Scientific American. The Winton, built in Ohio, was made by hand and came with a leather roof, padded seats, gas lamps, and tires made by B.F. Goodrich.

In 1907, John was only 9 years old when 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 1915, when he was 17 years old, the Germans first used poison gas as a weapon at the second Battle of Ypres during World War I. While noxious gases had been used since ancient times, this was the first use of poisonous gas - in this case, lethal chlorine gas - in modern war. Subsequently, the French and British - as well as the United States when they entered World War 1 - developed and used lethal gas in war.

In 1929, he was 31 years old when on October 29th (Black Tuesday), the stock market crashed in the United States. Billions of dollars were lost and some investors committed suicide as a result, having lost their fortunes. This ushered in the 12 year, worldwide Great Depression.

In 1946, in the year of John Etheridge Ryan's passing, pediatrician Dr. Benjamin Spock's book "The Common Sense Book of Baby and Child Care" was published. It sold half a million copies in the first six months. Aside from the Bible, it became the best selling book of the 20th century. A generation of Baby Boomers were raised by the advice of Dr. Spock.
