In 2001, Homeland Security Director Tom Ridge told a news conference that "thousands and thousands and thousands" of people had been tested for anthrax around the country but only a handful had tested positive for infection. FBI Director Robert Mueller meanwhile announced a million-dollar reward for information leading to the arrest and conviction of those responsible for sending anthrax-laden mail.
The "Wizard of Menlo Park" died on this date in 1931. Thomas Alva Edison, one of the most prolific inventors in history, was 84. His contribution to America's way of life was enormous, producing, among other things, the phonograph, the first practical incandescent light bulb, the first complete electrical distribution system for light and power, the world's first power plant, the alkaline battery and the first electric railroad.
Lee Harvey Oswald was born this date in 1929. President Kennedy's assumed assassin lived a troubled life and defected to the Soviet Union for a brief period -- only to decide to return to America.

The border between Maryland and Pennsylvania was finally settled on this date in 1776.

It was on this date in 1993 that a Los Angeles jury acquitted two black defendants of most of the charges brought them in connection with the beating of white truck driver Reginald Denny. As violence erupted in South-Central L.A. in late April 1992 -- following the acquittal of four white police officers in the 1991 videotaped beating of black motorist Rodney King -- Denny was dragged from his truck by rioters and almost killed. The attack was caught live by a TV news chopper.
And it was on this date in 1959 that the Soviet Union announced that an unmanned space vehicle had taken the first pictures of the far side of the moon.
