In 1896, in the year that Kathryn P Ott was born, in April, the first study on global warming due to CO2 - carbon dioxide - in the atmosphere was published by Swedish scientist Svante Arrhenius. Arrhenius concluded that human activity due to the Industrial Revolution would amplify CO2 in the atmosphere, causing a greenhouse effect. His conclusions have been extensively tested in the ensuing 100+ years and are still seen to hold true.

In 1906, when she was just 10 years old, President Theodore Roosevelt received the Nobel Prize for Peace. The award was considered controversial at the time because many thought that he was an imperialist. But he had brokered peace between Russia and Japan a year previous and had allowed a dispute between Mexico and the U.S. to go to arbitration, resolving the issue peacefully rather than resorting to military conflict. For these two reasons, the Nobel Prize committee chose him for the Peace Prize.

In 1945, Kathryn was 49 years old when on June 22nd, the Battle of Okinawa ended. A joint Army and Marine campaign, supported by the Navy, the Battle of Okinawa went on for 82 days. The last Japanese resistance on Okinawa was defeated. 4,907 Navy, 4,675 Army, and 2,938 Marine Corps personnel were killed in the battle on the US side. It is estimated that 110,071 on the Japanese side were killed - the estimate includes Okinawan citizens who were pressed into service and includes children. With the win of Okinawa, the United States gained an important base of operations in the Pacific.

In 1960, by the time she was 64 years old, on May 1st, an American CIA U-2 spy plane, piloted by Francis Gary Powers, was shot down by a surface-to-air missile over the Soviet Union. Powers ejected and survived but was captured. The U.S. claimed that the U-2 was a "weather plane" but Powers was convicted in the Soviet Union of espionage. He was released in 1962 after 1 year, 9 months and 10 days in prison.

In 1987, in the year of Kathryn P Ott's passing, was the first time that a criminal in the United States - a serial rapist - was convicted through the use of DNA evidence.
