SUMMARY:Gas-filled detectors: the Darwinian Champions of Particle Phys
 ics \, Physics Department Colloquium\, David Nygren\, Lawrence Berkele
 y National Laboratory
DESCRIPTION:The first detection of single ionizing events occurred mor
 e than 100 years ago when Ernest Rutherford and Hans Geiger succeeded 
 in recording alpha particles from radon decay using a gas-filled detec
 tor and an electrometer.  Remarkably diverse and useful innovations fo
 llowed and continue to emerge even today\, establishing gas-filled det
 ectors as the exemplary evolutionary survivors in nuclear and particle
  physics technique.  Although this ample record has many interesting c
 hapters\, I will focus on my favorite topics within this humble corner
  of the quest to understand our universe. The evolution of these devic
 es is interesting not only for their substantial contribution to exper
 iment\, but also for what was\, surprisingly\, overlooked as technolog
 y evolved.
