I, like John and George, never personally met or served with "Master Jack". However, from the testimonials put forth in the many posts and the reputation he so deservedly earned, it is evident that I missed someone who stood tall and proud among his shipmates.
Myself and Linda wish to add our sincere condolences and prayers for the Fessler family and that they will find some measure of comfort in knowing that he will be missed by the entire IUSS family, as well.
