"The world has lost an exceptional man who possessed a brilliant mind and, unfortunately,we have lost a dear and faithful friend. Dallas was a kind and generous person with a superior intellect who could quote answers to nutrition and scientific questions with amazing speed and always had the references to instantly support his replies. He possessed a remarkable sense of humor as well as the ability to inform you of being totally wrong without ever being offensive. His writing skills were well recognized and we used him often to proof read manuscripts. We could be assured that upon return, half the commas in the manuscript would be removed but the English would be remarkably improved . We will sorely miss the frequent communication via e mail and phone we had with him.He was our final source of truth on matters dealing with a host of subjects... dietary supplements, industrial gossip and politics to name a few. We will miss the good-natured responses he gave to our always friendly teasing. Farewell good friend and rest in peace. God Bless Dr.Harry Preuss and Bonnie Preuss"
