The first electrical detection of single ionizing events occurred more than 100 years ago when Ernest Rutherford and Hans Geiger succeeded in recording single alpha particles from radon decay using a gas-filled detector and an electrometer. Remarkably diverse innovations based on gas-filled devices followed and continue to enjoy importance in the arsenal of nuclear and particle physics techniques. Of course, detection techniques based on liquid and solid state devices flesh out this fascinating history. The evolution of all these devices is interesting not only for their enabling contributions to discovery, but in some cases, for aspects that were overlooked. Although this ample record has many interesting chapters, I will focus on topics familiar to me that seem best to illustrate how to make such advances.
