### Automobile Dealership

When my husband and I arrived at an automobile dealership to pick up our car, we were told the keys had been locked in it. We went to the service department and found a mechanic working feverishly to unlock the driver's side door. As I watched from the passenger side, I instinctively tried the door handle and discovered that it was unlocked. “Hey,” I announced to the technician, “it's open!” To which he replied, “I know — I already got that side.”

## Frank PressBorn 4 Dec 1924. American geophysicist known for his investigations of the structure of the Earth's crust and mantle and the mechanics of earthquakes. Press pioneered the use of seismic waves to explore subsurface geological structures and for his pioneering use of waves to explore Earth's deep interior. In 1950, with William Maurice Ewing, a major innovator in modern geology at Columbia University, he invented an improved seismograph,and they published a landmark paper recognized as beginning a new era in structural seismology. While at Caltech (1955-65) and later MIT, Press became known in public policy circles for his work on seismic detection of underground nuclear tests and for advocacating a national program for earthquake prediction capabilities. |
