Over this past weekend I found out that my colleague, friend and co-author, Gene C. Armistead, passed away peacefully on March 9. It was one of the great privileges of my life to have known and worked with Gene, and had it not been for his continued enthusiasm, encouragement and perseverance, our "Arch Rebel" would never have come to fruition. He will certainly live on in the hearts and minds of those who had the pleasure to know him and count him a friend.
