Dallas
A City on a Dry Crossing
Portrait
John Neely Bryan settled in 1839 at the one place the Trinity could be crossed dry — a ridge of Austin chalk under the mud that stopped everything else from late autumn to spring — so the city stands on a ford and has never had a navigable river. On 12 September 1958, at Texas Instruments on North Central Expressway, Jack Kilby demonstrated the first working integrated circuit.
