I thought I would be making Bob a get-well card and am shocked to be writing a memorial instead. Bob was the first of the Eckert sister babies, a treasure to be passed around while the men were off to war.
Bob and I made jokes about his responsibility of keeping me on the straight and narrow path- as he was my Godfather. I will always think of Bob so fondly, I remember him playing (not winning) the family card game of NUTTS, I remember him wearing a shirt protector for his pen, I remember his glasses when he was young, I remember calling and waking him in the middle of the night when Ann died. The rest of my memories are diluted with all of us at picnics with paddle ball and the never overlooked holiday dinners, the lake of the Ozarks and my first camping trip with the way experienced Teifenbrun family. I remember groaning as I watched endless home movies of Alaska as Bob listed every meal they ate (as he panned the ocean with the super-8 camera). How lucky we were to grow up as so many cousins in one city.
I am glad his life worked out so well, with the brilliant choice of computer science back when computers were the size of an entire room and most people were clueless as to what they were. The work -live -ski adventure in Colorado was also brilliant as was the return to his family for comfort in his later years. As always, now that he is gone, it occurs to me I would like to know more about how he came to these choices in his early life. RIP Bob, once again all of the aunts and uncles are waiting for you as they were in 1942.
Jill, I love your memorial. He was a great brother and spoiled his sister’s kids whenever he could.
Our lives were fun and full of family because of our cousins growing up together❤️
I remember staying with Bob in Denver on my way to see my son, who was working in Yellowstone. My few memories of him are as a kind, generous soul, very welcoming. I wish we could have spent more time together. Bob, you were a very special person.
Cathy thanks for your kind words. Bob always enjoyed seeing his cousins😇
