You can see his foot prints in many offices around the world where he visited

Dear Tim,
I am very sorry to learn about the passing of your father, Jimmy as I used to call him. It seems it was yesterday that I visited him in a southern surburb of Chicago. He took you and me to his favorite noodle house and we had a great time together. Jimmy is such a giant in his field, a great scholar and a gentleman. You can see his foot prints in many offices around the world where he visited - somewhere you can find a beautiful creation of a paper folded animal on the desk or book shelves.
Best regards,
Ken Chong
