In 1906, in the year that Charlotte E Kincaid was born, English biochemist Frederick Hopkins concluded that vitamins are essential to the human body and that a lack of vitamins caused scurvy and rickets. Scurvy and rickets were both huge problems in sailors that were at sea for extended time and the addition of vitamin C, vitamin D, and calcium in their diets helped eradicate the problem.

In 1913, by the time she was only 7 years old, ratified in February the 16th Amendment, establishing a Federal income tax, became law. Previously, customs duties (tariffs) and excise taxes were the primary sources of federal revenue. With the passage of the 16th Amendment, incomes of couples exceeding $4,000, as well as those of single persons earning $3,000 or more, were subject to a 1% Federal tax (that would be about $98,000 and $74,000 now). Rates rose to 7% for incomes over half a million dollars. Less than 1% of the population was subject to income tax.

In 1925, at the age of 19 years old, Charlotte was alive when in July, the Scopes Trial - often called the Scopes Monkey Trial - took place, prosecuting a substitute teacher for teaching evolution in school. Tennessee had enacted a law that said it was "unlawful to teach human evolution in any state-funded school". William Jennings Bryan headed the prosecution and Clarence Darrow headed the defense. The teacher was found guilty and fined $100. An appeal to the Supreme Court of Tennessee upheld the law but overturned the guilty verdict.

In 1968, she was 62 years old when on April 4th, Dr. Martin Luther King, Jr., the civil rights leader, was shot and killed by an assassin in Memphis. James Earl Ray was apprehended and plead guilty to shooting Dr. King. Ray died in jail in 1998.

In 1986, when she was 80 years old, on January 28th, the space shuttle Challenger exploded 73 seconds after launch. All seven crew members died. The cause of the explosion was later found to be a failed O-ring. The O-ring failure was due to the unusually cold conditions at Cape Canaveral.
