Dirck was gifted with many talents. He had an IQ that must have been in the four digits. He was good in sports and taught us to play baseball, soccer, croquet, badminton and more. He was always a straight A student. In my freshman year in High School I wanted to wear glasses to be like him only to find out my eyes would focus better but didn’t improve the focus of my mind to get better grades. As Dirck was the oldest and seemed to have all these talents, I asked Mom “why did he get all the “Smart Genes”. Mom would just chuckle and say “I love you all the same.” And she did love us all the same. Dirck also had a sense of humor. I remember in the Mendham house Dirck, Eric and I made a puppet theater from wood for a foundation for a round swimming pool we had in the back yard and used a curtain we could open and close. We had lots of stuffed animals and Steiff hand puppets and put on a show. Dirck even came up with a commercial for a new kids breakfast cereal called “Lost” which featured wonderful benefits and closed with the tag line... “so kids when your parents go out to the grocery store tell them to GET LOST!” The summer when we first moved into the Stillwater house Dirck and I decided to clean this old Remington desk typewriter so we took it all apart. When we put the parts all back together we had a few pieces left over. I didn’t work quite the same, but it was clean. So many great memories I will always cherish. Love and see you on the other side. Your brother Pete

My memories of Dirck:
While Dirck was the first of six kids, Liese and I represented the 2nd wave of Uptegrove progeny. Dirck was nearly a teenager before I arrived on the scene.
One of my earliest memories of Dirck was with Tippy the cat. I had gotten really gashed by Tippy multiple times by trying to carry him around like I could carry Cream Puff – by wrapping by both arms around him and 2/3’s of his body dangling back and forth like a stuffed animal. I remember being impressed that Dirck was able to handle Tippy without the associated blood-letting – (I thought my big brother was like a lion tamer). But Dirck’s affection for Tippy did not extend to my hamster. Mom provisioned me with a hamster in a cage that stayed in the bedroom all of us boys shared. Of course, the best time for a hamster to take a long journey on his squeaky exercise wheel was at night. Dirck’s solution to this annoyance was to stick a pencil thru the cage into the wheel so it could not rotate. However, I’m sure the hamster appreciated the many yellow “chew sticks” that Dirck provided.
Fast forward several years. Mom & Dad visited Dirck in his spartan digs at the Stevens Institute of Technology. Mom was scandalized that Dirck had only one dish, one bowl, one cup and one setting of silverware. Later, when news broke about this mysterious woman named “Liz”, we wondered how she was going to deal with this. Well, we needn’t have worried as Dirck and Liz formed a strong partnership with many shared interests including math, education, puzzles, music, books, travel and even kids!
As adults, Dirck and I both worked in similar high-tech fields and we would compare notes about work during family events. The age gap between us had pretty much disappeared. Like the rest of his siblings, Dirck was unable to escape inheriting Dad’s sense of humor. The frequent humorous repartee during family events and in emails was always fun.
Thank you Dirck, Liz, Gretel and Kirstin for taking care of Mom for so many years. And now, Dirck, your legacy is safe in Liz and the kids.
Farewell my brother, you will be missed by all of us!
Leif Uptegrove
P.S. Thank you Liese for not sticking with the clarinet …

Memories of Dirck
From my prospective, being the last of 6 kids and Dirck being the first, I always saw him as being reserved, highly intelligent, talented, and way ahead of most other earthlings. He was proficient at anything that he put his mind to. Whether it was math, the sciences, art, musical instruments, it seemed he was one step ahead of the rest.
Mom and Dad were so proud of him, especially when it was discovered that he had been offered grants from Julliard School of Music and Stevens Institute of Technology, and he simply had to pick which one to go to.
Thinking back, I remember a time when I was practicing my clarinet in the living room assuming that no one was around to hear the noise, not realizing that he was quietly in the next room analyzing what I was playing. Then when I paused, he gently interjected his critique and suggestions, which was an unexpected, pleasant surprise and extremely helpful! I just loved that he had such a tremendous appreciation for music.
Yet he had a keen sense of humor too, though we’re not all entirely sure how much he was amused by the goofy fake Gorilla at his 50th birthday party (LOL).
Dirck, our Leader of the Pack, a gifted, one of a kind brother who we greatly appreciate and will so very much miss.

My first memory of Dirck was at lunch in a small conference room at Xybion. He was a very quiet, reserved 20 something.
A year later, when the company moved to 7 Ridgedale Avenue, he sat in the farthest office with Dennis Badura, another quiet reserved man. My mission would be to get these serious men to smile. I’d make it a point to go into their office and call him Dircky Poo, which would always get a smile and a laugh out of both men.
Even though I haven’t seen Dirck over the past years, I will always remember that smile and laugh.

...New Jersey is the place to be.... (sung to the tune of Green Acres)
In a way, Dirck and that song are kind of linked at the hip for me. We grew up in New Jersey and Dirck spent the better part of his 79 years there. As the oldest of six siblings, he was in many ways, the leader of the band. I have always maintained that Dirck got the brains, Heidi and Liese got the looks, Leif got the money and Pieter and I were left out in the cold (Insert the official Uptegrove Coat of Arms).
I learned at an early age that Dirck was going to be a hard act to follow. For example, when he was taking piano lessons I whined to dad that I needed to learn the piano too. That’s where he learned to read music and I learned I had two left hands. There was another time dad took Dirck to get eyeglasses and I whined to dad that I needed glasses too. So the optometrist did the eye exam and told dad that although Dirck did need glasses, my eyes were fine but there seemed to just be a disconnect between my optic nerves and my cerebrum.
Dirck was genius level smart to me. He was also the last person I knew who actually was able to solve complex mathmatical equations with a slide rule. I used it to draw straight lines on paper with a pencil. As a student, Dirck would cry if he got an A minus. I celebrated if I got an F+.
Dirck excelled at art - like oil painting - where I had trouble mastering finger paints (the white paste was tasty however). He also worked and earned his way through college which led him to one of the longest careers in doing the same job in the same spot for multiple companies. I often thought he just got a table and chair and they built the building around him.
As well as the piano, Dirck excelled at the flute - maybe excelled is too mild a word - then, when the girls came along he learned to play the violin (which he may have borrowed from Jack Benny.) Once, when we were in the Stillwater house, I was playing Greensleeves on the guitar. Dirck got some blank music sheets and proceeded to have me stop and start playing the song until he had it all down on paper. When he was finished he showed me the results - I was utterly gob-smacked - it looked like somebody had spilled an ant farm all over the page. More impressive is he could make heads and tales of it and then play it.
When I was about 5, it is a little known fact that, in spite of Dirck’s mild manner and Clark Kent glasses, he was really the mastermind behind “The Great Christmas Caper of 1954”. We used to put up the Christmas tree on Christmas eve. We decorated it with the usual odd assortment of ornaments and a long paper chain we kids hand crafted and added to every year. (At one point I’m sure, if layed out straight, would have reached to the moon and back). We did all the normal Christmas eve things, and right before bedtime hung the stockings (with care) and then were forced marched to the bedroom to suffer through the long night until daylight - when we could finally open our presents. This year, however, would be different. Dirck led the conspiracy to do the bold and unexpected. He and Iwould wait until mom and dad were asleep and Santa had time to deliver the goods and then do a stealth raid on the presents under the tree! So, in the wee hours of Christmas morning we snuck quietly out of the bedroom and made our way slowly and stealthily to the tree. We first made sure that Santa had taken the bribe of milk and cookies we set out for him. Good, bribe taken and there was treasure under the tree. So far, Dirck’s plan was working to perfection...so we sat there passing presents back and forth, hefting them, shaking them, squeezing them and guessing what they might be - - - when one that I was checking went POP!!!! The sound echoed through the house like a gigantic peal of thunder! That sent us scurrying back to the bedroom, back into our beds and pretended we were there blissfully dreaming of dancing sugar plums. Dad, to say the least, was not tricked or amused. So much so, that he got a broom and used it to prop the bedroom door shut! We were caged! Somehow I think dad blamed me (halo and all) instead of Dirck, but in the end it worked out as the present that created the POP was the cellophane window of the box holding what would become my favorite stuffed animal...Kanga and it the pouch, Roo. (Somehow I also got the blame for “The Great Hillcrest Avenue Acorn Wars” but that was probably only because Dirck had that mild mannered intellectual personna and - - - those glasses!).
From puppet shows to an array of younger siblings, a large menagerie of pets and several house moves, Dirck went on to higher education, marriage, two daughters, two grandchildren, and, amazingly enough, all in New Jesrsey. So, how do you condense a lifetime into a few paragraphs? Dirck was always just there, even when he wasn’t. (That will make sense to some) Hard to try to follow in an older sibling’s footsteps. As it turned out, two roads diverged in a wood...
One last thought about Dirck provided to me by mom. When she brought me home, she told me he looked at me for a while, looked at her and said “that’s nice mom, when are you going to take him back?” Poor Dirck, he was saddled with me right up until the last.
Farewell, brother
Eric

We played Bridge with Dirk and Liz many times. I remember once coming over and Dirk was solving some differential equations on paper for fun and as he said “to keep my memory in good shape”, or something along those lines. I never worked with him, but that must’ve been a great experience. - James Jeude

Heidi’s Memories of Dirck-
Six kids, Dirck, being the oldest, was a very hard act to follow for the rest of us siblings.
Dirck loved science. Chemistry kits, Erector sets were his toys of choice.
He loved watching a TV show called “Watch Mr. Wizard”, a science show doing experiments designed for kids. We would watch right along with him.
He loved classical music, listening to it and playing it beautifully on piano and flute. I loved listening to him practice his lessons,
so masterfully done. As an adult he added guitar and violin to his skills.
He loved math, I was astonished at how he could figure out the notes to a song on guitar by using math. (I can barely do math using my fingers to count on).
When it came to art, he would bring home oil paintings, other pieces of art home from High school that were done so well.
He enjoyed humor, as a youngster,
Mad Magazine was a favorite of his. Movies like the Marx Brothers, Laurel and Hardy always made him laugh.
Dirck was even an excellent tailor. When he was around 8 or 9, he decided that his old stuffed buddy, T- Bear, needed some clothes. He found some old scraps, plaid flannel and corduroy, then cut to shape and hand sewed
T- Bear’s flannel shirt and corduroy pants. (I have old T- Bear and he still wears this outfit)
The other aspect of Dirck, is that he was a shy person, not comfortable being the center of attention.
One memory that always makes me and the rest of the family laugh, is when Dirck reached
his 50th birthday.
All us siblings decided to give him
a surprise party. We hired someone in a gorilla suit, wearing a banana necklace, to sing him a birthday song with lyrics we wrote, to be sung to the tune of “Gilligan’s Island”. It was priceless to see Dirck wearing the banana necklace that the “gorilla”, placed around his neck and holding, the stuffed gorilla that was presented to him when the song was done. At the time, I think he would have loved to become invisible…
He always laughed when we brought up this memory. Farewell Dirck, we miss you.
