Friedrich Wilhelm August Argelander is generally considered the father of variable star astronomy. He was the first astronomer to begin a careful study of variable stars. At the time, only a handful of variables were known, and he was responsible for introducing the modern system of naming them using the capital letters R-Z.

If you’re like most people, you do your major giving toward the end of the year. This is also the time of year most non-profit organizations receive over half their donations for the calendar year.
