Wes Fulton and Dr. Bob Abernethy would like to thank Paul Barringer, John Fulton, Nozar Jafarey, Patrick Heatherington, and Kevin Van Fleet for helping us onto the WWW. Others who deserve recognition for help in this area are Jorge Granada, Vicky Peralta, and Ivan Cala. We also appreciate the recognition of our minimum packaging efforts in all our products and our contributions to reducing the unnecessary distribution of paper. This web site keeps that tradition and will remain relatively free of unnecessary and cumbersome graphics or at least will have a warning. Our purpose is to provide useful promotional information, not artwork.

Dr. Bob Abernethy wrote the first Weibull Handbook. Wes Fulton wrote the first widely used Weibull software. They have been developing Weibull PC software for over thirty years, much longer than anyone else. There is no more complete Weibull analysis program available or even close in specific Weibull capability. Many of the features are not available elsewhere.
