From Texas Standard:
Certain events in history have changed the lives of Texans forever. The Great Storm of 1900 in Galveston is still the deadliest hurricane on record. On a day in Dallas, in 1963, a nation lost a president. In 1966, a shooter atop the UT Tower terrorized a city by committing the first mass murder on a college campus. And now Harvey. These defining moments are embedded in the memories of those who lived them, but for everyone else, we rely on the written record.
