    I was greatly saddened of hearing of Jose's passing. He was one of my greatest friends and co-worker at DuPont. We both shared a great enthusiasm for science, flying and orchids. We had several patents that we developed together that I am very proud of. I will greatly miss you my friend. Pat McIntyre.

    To the Valentini family, I had the pleasure of working for Jose for a couple of years at Dupont. He was a wonderful boss. Very caring, gave great direction, and highly respected. Every time we met in his office, he would slide a piece of chocolate across his desk to me. What a nice memory. I pray your family finds peace during this sad time. Christine

    Liebe Familie, Ich drücke mein tiefstes Beileid aus. Ich hatte das grosse Glück, Jose für einige Jahre in der Schweiz als Vorgesetzten zu haben. Er war stets für alles offen und sehr bestrebt, sein Wissen zu teilen und weiterzugeben. Ich und meine Kollegen vermissen ihn sehr. Er brachte jeden Tag die Sonne und gute Laune ins Haus. Es gab nicht viele, welche mein Leben in so kurzer Zeit so geprägt haben. Geri

    Ralph Waldo Emmerson said, “The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.” Some people spend an entire lifetime wondering if they made a difference in the world, but Jose Valentini didn’t have that problem. Jose was a man of great intellect, drive, and ingenuity. Here the record stands through his education and life’s work as a scientist and instructor. What is more, he was a person of great love, compassion, and integrity. I will always remember Jose as a man whose life spoke volumes. This was especially made clear in his love for his family, friends, and God; and their love for him. As such, Jose Esteban Valentini not only lived life well, but was equally happy in doing so. Silvia, Bryan, and Romina, I am so sorry for your loss, but I am confident that while Jose’s mind and body were encumbered by illness in his final days, those restraints are now lifted. He is himself again - more himself than at any time on this earth. For we may be sure that the Lord never forgets those who remember Him, and as the last journey of this faithful pilgrim took him beyond the sunset, and as heaven's morning broke, I like to think - in the words of John Bunyan, that “all the trumpets sounded on the other side.” We here still move in twilight, but we have one beacon to guide us that Jose Valentini never had. We have his example. Let us give thanks today for a life that achieved so much for us all. God bless. . . Jack Hickey, Sr.

    I had the pleasure of working many years with Jose at DuPont. He was always a kind and generous soul; always had a smile and a piece of chocolate for you. He left us way too early. Deepest condolences to the Valentini family. Be comforted knowing that he is now flying with the angels.

    I worked with Jose at DuPont and knew him outside of work from our shared love of flying. I'm so sorry to hear Jose passed. He always had a smile and I enjoyed our conversations both technical and about flying. I'll miss him.

    I had the great pleasure of meeting Dr. Valentini through working with him as a student assistant at Delaware State University. He was one of the kindest individuals I have ever met, he always made sure the students were understanding any aviation material covered. I will miss having him as part of our DSU family. , Kyle Longhany
