1896 - In the year that Gillis Mcmanus 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.

1913 - He was 17 years old when 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.

1921 - At the age of 25 years old, Gillis was alive when in May, the Emergency Quota Act - or Emergency Immigration Act - was passed. The law restricted the number of immigrants to 357,000 per year. It also established an immigration quota in which only 3 per cent of the total population of any ethnic group already in the USA in 1910, could be admitted to America after 1921. Although the Act was supposed to be temporary, it stayed in effect until 1965.

1954 - By the time he was 58 years old, on May 17th, the Supreme Court released a decision on Brown v. Board of Education of Topeka. The ruling stated that state laws establishing separate public schools for black and white students was unconstitutional thus paving the way for integration in schools.

1979 - In the year of Gillis Mcmanus's passing, on November 4th, Iranian militant students seized the US embassy in Teheran and held 52 American citizens and diplomats hostage for 444 days. They were released at the end of the inauguration speech of the newly elected Ronald Reagan.
