materials under stress. Dad was a caring father, who followed silently 10 feet behind me on my first trip by public bus to school (to make sure I arrived safely), who took his children on hikes, and who coached me on multivariable calculus when I resumed my studies in mathematics and physics after a one-year hiatus at Stanford-in-Germany. He was a devoted husband who supported my Mum’s many passions and idealism. He would use a clothespin to replace a lost button on his coat, and his desk at Stanford was piled so high with papers that he had to work on the pullout shelf. But he could always find an important paper in one of the piles. As long as he had clothespins to keep himself together, Dad did not need the material trappings of life such as stylish clothes, fine meals and accommodations, hobbies, or indulgences of any sort. He did not covet awards and prizes, and yet many were bestowed upon him. He found great satisfaction in his profession, his family, and his daily walk, and for him, this was enough.
