To the Throop family - our most sincere condolences in the loss of a terrific person. Irwin was a great help to Bob when he first started in Materials Management at DuPont. He was always a real "gentle man" and well thought of by his peers. We are sorry that we will not be able to attend the service or gathering afterwards due to a previous commitment. Bob had a good talk with Irwin about a month ago by telephone. Again our regrets but our thoughts and prayers are with all of you at this difficult time. Sincerely, Bob Hudson and Sharron Botham (retirees of DuPont/Invista)
