Dr. John James DeLuisi beloved husband, father, grandfather, brother and uncle passed away February 26, 2019. He was 88. He is survived by his five children, John Jr., Barb, Rebecca, Nan and Michael; nine grandchildren; sister Vincenza Maruszak; sister-in-law Sandra Furlo; seven nieces, five nephews; and cousins in the U.S. and Italy. John was born in Little Falls, NY to his Italian immigrant parents John and Anna DeLuisi. John enjoyed retelling the stories of his happy and carefree childhood spent roaming and playing in the nearby woods of Little Falls. From an early age, he had an interest in science and mathematics. After graduating from high school, John joined the United States Navy in 1948 and entered the Navy Reserve in 1949. He was recalled to active duty in 1951 and served two more years during the Korean War. John valued education, earning a B.S. degree in Mathematics from New York State College for Teachers in Albany in 1957, and then earning a Master's degree in Mathematics in 1958. After graduating, he taught biology, chemistry and physics at a high school in East Greenbush, NY. He attended Brown University in 1961, earning a Master's degree in Science Education on a National Science Foundation Scholarship. From 1962-1967, he attended Florida State University in Tallahassee. He earned his PhD in Meteorology in 1967. John met Prudy Williams, the love of his life, in 1958 while both were attending college. For John, it was love at first sight. They married in 1959 in Granville, NY and were happily married for 57 years. John and Prudy moved to Colorado in 1967. They lived in and around the Denver metro area for 10 years and settled in Boulder in 1978. John spent the bulk of his career at NOAA in Boulder. With NOAA, he traveled the world collaborating with many international atmospheric scientists and organizations. He was one of the world's experts in the study and investigation of the interaction of solar radiation with the Earth's atmosphere. John initiated and developed the U.S. SURFRAD network, which has become NOAA's longest running and most successful surface radiation network. During his career he also mentored many young scientists. John will be greatly missed by his family, friends and colleagues. The DeLuisi household was always a popular gathering place for friends and family. John and Prudy were well known for their superb culinary skills and warm hospitality. Their gatherings were filled with great food, plenty of beer and wine and an abundance of love and laughter. John will be remembered for his affection, wit, intelligence and a full life lived with adventure, passion, integrity and love. A celebration of John's life will take place Thursday, March 7, 2019 at 2:00 p.m. at Sacred Heart of Mary Church in Boulder.

John DeLuisi was an astonishingly productive atmospheric scientist. He was especially known for his studies of the ozone layer and solar ultraviolet. One of his papers on ozone had a major impact on my development of a miniature device to measure the ozone layer. I used wavelengths he recommended, and this made my handheld instrument as accurate as much more costly professional ones. When I introduced my father to John at his office in Boulder, he took time from his busy schedule to answer my dad's questions. They parted as friends. I cherish the times John provided scientific advice and will always be thankful for his role in my career. May the Good Lord bless John DeLuisi and his extended family.

I have many fond memories of my brother John. When he was young, he loved to go to Moreland Park in Little Falls and roam in the woods. He loved the outdoors. Memories I will treasure forever, are my visits to Colorado and John and Prudy's visits to Florida. I remember a trip I took with John and Prudy to Italy. We visited relatives on my mother's side of the family. It was my first trip to Europe, and truly a memorable experience that I will cherish for a lifetime. John lived his life to the fullest, and touched so many people during his time here with us. He loved his family and was a caring and respectful man. Whether you needed advice, or a shoulder to lean on, he was there for you. Thank you for being part of my life, along with my children. Miss talking to you on the phone. Rest in peace my brother. You'll be always on my mind, forever in my heart. I miss you and love you. Together forever with Prudy in heaven.

God Bless & Much Love,

I have very fond memories of Uncle John that I will always cherish. He was a very caring and loving person. He was a man of wisdom and a person with a kind heart. One of my all time favorite memories, was a trip I took to Colorado when his children were young. Uncle John packed the camper and took all of us up into the mountains for the day. It was my first time in the mountains. I was in awe of the beauty of Colorado. I know that you're not with us anymore and I know that you're looking down on us everyday. I love you and will miss you dearly. Reunited together with Aunt Prudy in heaven.

God Bless & Much Love,

Barb: I am very sorry to hear of John's passing. We just found out about it yesterday. Sandy and I have very fond memories of their visit to us here in NC and of the dinners Mom would fix at their place. John was a great help and friend for me especially. I took on the EPA UV monitoring program in the early 1990's and frequently came to him for advice and help. Without his guidance I would have been lost!! He also gave me great support on my PhD project and was one of my thesis committee members. I'm sorry we didn't get to see each other during the last few years. He was a great friend and extraordinary scientist!

Love from us both,
Bill and Sandy Barnard

I have many fond memories of time spent with your family. John was always inviting anyone who dropped by to stay for dinner, or at least a glass of wine. He was well-read in so many subjects and eager to pass on his knowledge. Above all, he loved his family and spending time with them. Treasure all your memories. Dixie George

I have many found memories of Uncle John and his love for family, the outdoors and life. I enjoyed the talks and visits. His unique personality and strong ethics made you listen for those bits of advice that came from years of experience and love. Uncle John's love for salt water offered us several trips when he visited Florida, starting with clamming on the flats in our bare feet. He was amazed at the art of clamming as we filled a cooler with huge clams. It was like finding gold to him, evidenced by his great big smile. On his next visit the fishing was slow but he caught the largest salt water trout I had every seen. The next trip we amazingly caught our limit of grouper. He was exhausted, but it was worth it. Our last visit was the same outcome except we stopped short of exhaustion. We ate what we caught cooked up by Uncle John.
I will miss those speaker phone calls with Uncle John and Aunt Prudy, a great couple reunited together.

God Bless Uncle John and Aunt Prudy

I have very fond memories of John. He offered me great work advice and guidance when I needed it most. I was happy to see him, albeit briefly, at the Global Monitoring Annual Conference.

My condolences to the family. Dr. DeLuisi was a wonderful person and I am honored to have known him.

Sincerely, Ann Thorne
