Andrew Harris (born 1952)

In 1952, in the year that Andrew Harris was born, on July 2, Dr. Jonas E. Salk tested the first dead-virus polio vaccine on 43 children. The worst epidemic of polio had broken out that year - in the U.S. there were 58,000 cases reported. Of these, 3,145 people had died and 21,269 were left with mild to disabling paralysis.

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. Working with "Freedom Summer", they were registering African-Americans to vote in the Southern states. Their bodies were found two months later. 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 1971, in March, Intel shipped the first microprocessor to Busicom, a Japanese manufacturer of calculators. The microprocessor has since allowed computers to become smaller and faster, leading to smaller and more versatile handheld devices, home computers, and supercomputers.

In 1989, on March 24th, the Exxon Valdez, an oil tanker, struck a reef in Alaska's Prince William Sound and oil began spilling out of the hold. The oil would eventually contaminate more than a thousand miles of coastline. It is estimated that over 10.8 million gallons of crude oil spilled into the Sound - killing 100,000 to 250,000 seabirds, over 2,800 sea otters, about 12 river otters, 300 harbor seals, 247 bald eagles, and 22 orcas - as well as an unknown number of salmon and herring.

In 1995, on May 19th, the deadliest terrorist attack on American soil - before 9/11 - took place in Oklahoma City. A truck bomb went off outside the Alfred P. Murrah Federal Building in downtown - killing 68 people, injuring more than 680 others, and destroying one-third of the building. The most disturbing images were of children - a daycare center was hit by the bomb. The deadliest incident of domestic terrorism ever, Timothy McVeigh, Terry Nichols, and Michael Fortier were convicted of the bombing.
