A Word of Thanks
I wish to thank my mother, Lynn Widrich, for her patience and guidance in helping me to deal with the death of my father, for the countless hours that she spent listening to my ideas and for her help in editing and publishing this book; to my step-father, David Greenstein, for making helpful practical suggestions; to Stephen M. Robinson Ph.D. for his insight and encouragement; to David Allen for
his invaluable computer expertise that made it possible to publish this book and to my family for their ongoing support. I would also like to give special recognition to my grandmother, the late Ruth Greenstein, for the artistic illustrations that she created for this book.
