HISTORY

Highlight: In 1964, the Free Speech Movement began at the University of California, Berkeley, as students spontaneously protested the arrest of Berkeley alumnus Jack Weinberg, who had refused to identify himself to campus police as he sat behind a table promoting the Congress of Racial Equality.

In 1885, special delivery mail service began in the United States.

In 1908, Henry Ford introduced his Model T automobile to the market.

In 1932, Babe Ruth of the New York Yankees made his supposed “called shot,” hitting a home run against Chicago’s Charlie Root in the fifth inning of Game 3 of the World Series, won by the New York Yankees 7-5 at Wrigley Field.

In 1939, Winston Churchill described Russia as “a riddle wrapped in a mystery inside an enigma” during a radio address on the invasion of Poland by Nazi Germany and the Soviet Union.

In 1949, Mao Zedong proclaimed the People’s Republic of China during a ceremony in Beijing. A 42-day strike by the United Steelworkers of America began over the issue of retirement benefits.

In 1957, the motto “In God We Trust” began appearing on U.S. paper currency.

In 1961, Roger Maris of the New York Yankees hit his 61st home run, which came during a 162-game season, compared to Babe Ruth’s 60 home runs during a 154-game season. (Tracy Stallard of the Boston Red Sox gave up the home run; the Yankees won 1-0.)

In 1987, eight people were killed when an earthquake measuring magnitude 5.9 struck the Los Angeles area.

In 1994, National Hockey League team owners began a 103-day lockout of their players.

Ten years ago: Mount St. Helens in Washington state erupted for the first time in 18 years but without nearly the force of the 1980 disaster. Police found the body of Lori Hacking in a landfill after picking through the trash for weeks in a search for the young Utah woman murdered by her husband, Mark.

Five years ago: The U.S. and five other world powers held high-stakes talks with Iran in Geneva to demand a freeze of its nuclear activities; President Barack Obama, in Washington, called the discussions “a constructive beginning.” David Letterman publicly acknowledged having had sexual relationships with some female staffers as “48 Hours Mystery” producer Joe Halderman was charged in a blackmail plot against the CBS “Late Show” host.

One year ago: The federal government partly shut down because of a budget impasse in Congress, the same day Americans got their first chance to shop for health insurance using the online marketplaces that were at the heart of President Barack Obama’s health care overhaul. (Government websites designed to sell the policies, however, struggled to handle the traffic, with many frustrated users reporting trouble setting up accounts).
