Whenever I think of Grandpa, two of his traits stand out, and make him incredibly unique.  The first was his love for his craft.  Most people would count themselves lucky if they were fairly satisfied with their jobs, but Grandpa's passion was on a completely different level.  Long after he was officially 'retired' Grandpa was working hard on Calphad projects.  He traveled the globe to attend conferences and confer with fellow scientists on pressing matters in the field. While his impact and achievements are well known, there aren't words to describe the spark that entered his eyes when he started talking about MIT or phase diagrams.  

Another thing that made Grandpa so special was his tireless care for others.  Well into the twilight years of her life, Grandpa's mother-in-law needed care that only he could deliver.  Without complaint, Grandpa would come visit her on a regular basis, deliver fresh laundry and take home the new loads. He would drive her to doctors visits and tend to her needs.  Grandpa treated Bobeh with dignity and respect; he was the ultimate son-in-law.
