May 9, 1928 –
 October 17, 2021


James “Jim” Delmore Marquardt, age 93, joined his loved ones in heaven on Sunday, October 17, 2021 in Dallas, TX.    Jim was born on May 9, 1928 in Moorhead, MN to Leonard and Alma (Grabinski) Marquardt.

Jim no longer has to “hit the gym” and has moved on to Jesus’ care. He lived a life of smiles, learning and giving and was not one to give up or back off. During the Great Depression, his parents and siblings guided him thru difficult times.  In high school he was active in gymnastics football, and swimming, earning the Eagle Scout award which lead to living a life of honor.

Jim served in the Army during World War II, along with his four brothers, Marlin, Robert, Wilbur (Bud), and John. Jim was proud of serving in the 82nd Airborne Division as an aviation mechanic. Their sister Alma was a Veteran of her five brothers!

North Dakota State University and the G.I. Bill provided a degree in Mechanical Engineering and Management. While there Jim still found the time and energy to join five friends and develop and operate the Detroit Mountain ski areas (Winter Holiday Ski Club) as well as forming a lifetime bond of friendship with them. Jim married the mother of his children, Helen Thistlethwaite during his years at NDSU. After graduation, Jim received an ROTC commission as a 2nd LT in the Air Force Reserve and later earning the rank of 1st LT. He also received his pilot’s license for single  engine land.

Upon graduation, Jim joined Minneapolis Honeywell and assisted in the development and production of the Honeywell round thermostat. In 1955 Jim moved to Phoenix, AZ to join AiResearch Mfg of Arizona. He spent the next 36 years in development, testing and production of a wide variety of products such as aircraft turbine engines, high altitude testing and development of a nuclear powered space system for a moon base. He spent the final 6 years as a company representative to the FAA certification acceptance.

It was in Phoenix that Jim met and married Lynda Powell Bebout in 1982. Upon Jim’s retirement in 1992, Jim and Lynda moved to Dallas, TX where Jim, authorized as an FAA Designated Engineering Representative (DER), travelled throughout the US and Canada as a consultant for repair stations. Jim and Lynda also shared their love of Brittany Spaniels rescuing and welcoming several  into their family over the years and actively supporting the BRIT Rescue in Texas.

Jim loved to volunteer at the Frontiers of Flight Museum at Love Field in Dallas sharing his passion for aviation and flying.  He was also an Ambassador at the DFW airport for over 15 years, assisting travelers negotiate through the massive complex, paying special attention to military personnel and veterans and showing appreciation for their service. 

Jim was preceded in death by his parents, brothers, and sister. Jim lost Lynda, his wife of 39 years, in June of this year.

Survivors include his three children: daughter Leslie Silverberg (Rob), son Mitchel Marquardt (Susan) of Gilbert, AZ and son Jim (Norman) of Key West, Florida; two granddaughters Kristen Cox (Caleb) and Kathryn Marquardt; Lynda’s brother Larry Powell (Joyce) and his family, Sam Powell (Cass), Casey Powell, and Delaney Powell as well as many nieces and nephews.

    My uncle/godfather was an amazing man. I remember times when he would share family stories with me. I will always remember his love for peanut butter. My mom even painted a jiffy jar for him. I will miss him, talking and sharing the “good ol’ days” with him. I know for sure and rest easy knowing you are with the lord and loving seeing your siblings again. BTW say hi for me. I will always love and miss you. Rest easy uncle Jim…..

    I was sorry to hear of the passing of Jim. I enjoyed reading of Jim’s very accomplished life. I was a friend of Lynda’s for 50+ years and know she was waiting for Jim when he got to Heaven.

    I was with Jim’s wife, Lynda, when they met poolside, back in 1980 and since Lynda was my very best friend for life, I was blessed to be a part of their lives for over 40 years. I always found Jim to be a first-class guy who loved his family, his country and his God fiercely. He was proud of his accomplishments in life, as he well should have been, and of his three children and his two granddaughters. I always looked forward to getting updates from Jim during our many visits together over the years. Although we lived far apart in miles, there was never a time that we didn’t get to see each other on at least two occasions annually (until Covid hit). I will always remember Jim as a dear friend who welcomed me into his home and graciously included my family in his circle of hospitality.

    I fondly remember Jim charming my grandmother and great-aunt when they came to visit me in Arizona. He barbequed up a fantastic meal and provided some great dinner conversation. If my parents were visiting, no problem, they were warmly welcomed into Jim and Lynda’s home as well.

    We disagreed on politics and the quality of Trader Joe’s wine, but respected each other’s opinions and could even laugh about it. Our mutual love for Lynda bound us together as dear friends.

    Thanks to Joyce, I was able to have a nice, long conversation with Jim the week of his passing. I will always treasure the memory of that, especially the fact that we were able to say “I love you” one last time. Jim was so appreciative of the many kindnesses that were shown to him by others. He was a true gentleman and I will forever miss him.

    Rest in Peace, Jim. May the angels watch over you for all eternity!

"If I could give 6 stars I would. Aria made a difficult easier to deal with by basically taking care of everything in an efficient but very empathetic manner. I can speak highly enough of Dusty Martin, who helped us with all of the planning and logistics. He was incredibly understanding and helpful."

"Nothing prepares you for the grief you go through when losing a child. I called this funeral home at 2:00 am broken and could barely talk. The amount of compassion and empathy they showed me immediately let me know I found the right place to cremate my son. I cannot thank them enough for their professionalism, SINCERE concern, and commitment to making sure my son was honored in the most respectful way. I hope this Funeral home values her as much as my family and I do."

"I can’t say enough about how helpful and professional Dusty Martin, the funeral director at the Aria Cremation location on NW Highway has been. From my initial call, he was kind and informative. My friend died at home while on hospice and she was picked up in about an hour after receiving the call from the hospice nurse. The person who arrived to pick her up was also very professional/respectful and allowed us to take as much time with her as we wished. When I met with Dusty the next day about arrangements, he explained the process and options available without being pushy or trying to “sell” extras. Throughout the process, he kept me informed and, for example, was careful to be certain I understood the cost of the obituary I wanted and offered some options for reducing that cost if I wished. When I stopped by for another reason and started talking about some of the problems I was having with the pictures and media I hoped to use at a memorial lunch I was planning, he not only listened patiently but offered technology advice and let me use his personal media player. I have had experience arranging cremations for four others using two other local companies, and this experience with Dusty at Aria has been by far the best one I have had."

"My Daddy’s service and our family experience at Aria Northwest Highway was truly blessed. Funeral Director Dustin Martin is the kind of person that you would like to see on a more regular basis – but in his industry – you hope to not see him that often. That being said – THANK YOU DUSTIN for your unending kindness, compassion and friendship through the process. Meeting you and discussing Dallas History, Find A Grave and my Dad’s lifelong contributions to the great City of Dallas was simply wonderful! In memory of my dad James A. Dodd, Sr. – I want to personally thank you and let you know that you made everything better in that moment. Your calling to “Be There” is spot on. Aria has a one in a million guy in you! Bling Blinky of TEXAS Shout Out: God Bless You!!"
