In 1914, in the year that Margaret A McLinn Collins was born, in August, the Panama Canal opened to traffic. Begun by the French in the 1880's and abandoned, the United States undertook further construction in 1904.

In 1920, on November 2, radio station KDKA began broadcasting in Pittsburgh, PA. This was the first commercial radio broadcast in the United States. Westinghouse, a leading manufacturer of radios and the backer of the station, chose the date because of the Presidential election.

Four years later, there were 600 commercial stations broadcasting in the U.S.

In 1964, in June, three young civil rights workers - Andrew Goodman and Mickey Schwerner from New York City, and James Chaney from Meridian, Mississippi - were kidnapped and murdered in Mississippi.

Although it was discovered that the White Knights of the Ku Klux Klan, the Neshoba County Sheriff's Office and the Philadelphia, Mississippi Police Department were involved, only 7 men were convicted and served less than six years.

In 1970, on May 1st, US troops invaded Cambodia, expanding the Vietnam War. The invasion of Cambodia was a Nixon policy, although it was argued against by both his Secretary of State and his Secretary of Defense.
