Jon Person is a component developer for desktop and mobile devices using .NET. His company, "GeoFrameworks," maintains the award-winning “GPS.NET” component now in use by hundreds of companies around the globe. Jon's articles have appeared in Dr. Dobb's Journal and have earned him the rank of one of CodeProject's "Most Helpful Members of 2004." In his spare time, Jon enjoys storm chasing in the Great Plains. On May 4th, 2007, Jon witnessed the two-mile-wide tornado that destroyed Greensburg, Kansas. He then volunteered for a month to help residents reclaim their lives, running GeoFrameworks from a hotel room with no TV or running water and using his GPS and .NET mapping component GIS.NET to manage volunteer jobs around the stricken town. A photo journal of this experience is up on Flickr.
